Title: Diesel knock harsh noise since remap GTD 170 (solved with Revo software)
Post by: Marshy on 29 June 2013, 20:25
I had my remap done nearly 3 months ago and noticed the difference in engine noise right away. Since having warmer weather and having windows down etc its really annoying me now and I want it sorted.
I found the engine note seemed more harsh with diesel knock at low rpms.
I've compared 2 other cr 170's and found them very quiet with the engine note getting quieter when lifting off idle.
Before remap mine was like this but not anymore.
I'm going to log my car and my dads cr 170 does anyone know what to log?
Timing etc?
Here's a some videos any input would be very helpful

I've not travelled to them yet but have been in contact via email etc.
I've not had a reply since Thursday!
Going to log cars today and ring them tomorrow.

Not an easy car to remap properly I'd say :-)

Tell me about it.
I've learnt the hard way. I returned yesterday and had a revised map which has made the engine less harsh but now the car sounds like its got a boost leak!
I've replaced the intercooler I-rings and pressure tested the intercooler and all the pipework up to 28 psi and have no boost leak.
I'm sure its a problem in the mapping now and wish if left the car standard.
Now I'm nearly £400 lighter and my car isn't right.

Get them to put it back to standard and claim your money back

Post by: Marshy on 10 July 2013, 18:34
I asked them to put it back to standard yesterday and enquiried about getting a refund but I was told there was nothing wrong with the software!!!!!
At the moment its spoiled my car and it looks like its going to cost me to fix!

Wasted 3 days trying to sort my car.
On Tuesday I returned to Sedox performance due to my harsh diesel knock on my cr170. After getting a revised map flashed my car then sounded like it had a boost leak!
After road testing and having lack of power another 3 different files were flashes on and none were any better.
After leaving with the first revised map and poor power and performance I limped the 90 miles home.
I've spent the last couple of days replacing the intercooler o-ring seals and pressure testing all the pipework from the turbo to the throttle body all if which is leak free as I tested it up to 28psi.
I've researched the turbo actuator problem but the vacuum side works perfect and no vacuum loss. I've tried disconnecting the airflow meter which doesn't make any difference.
I logged the car lastnight and it does eventually make target boost pressure but higher up the revs than previous.
Anyone any ideas?

How firm were you about requesting removal of the map and a refund?  Perhaps you need to be more insistent and kick up a fuss.
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 11 July 2013, 21:38
I asked 3 times but was told that it wasn't a software problem so no.
I don't understand how it can drive 90 miles there with plenty power and then get flashed and then sound like its got a boost leak?
Then be told its not software!
I even offered to pay the difference for Revo but that didn't happen either.
Although they have Revo signs advertising according to the Revo website they're not listed as an authorised dealer.

Get in contact with your local Trading Standards and see if they can offer a solution

To me its very poor customer service on their part............

Would they even agree to put you back to standard??  :huh:
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 12 July 2013, 06:56
They didn't want to put it to standard because they said it would lock the ecu again!

If it were me i would have put you back to standard, carried out a diagnostic check, then remapped the cqr again and carried out more diagnostics to ensure it wasnt the software at fault

You dont simply dismiss customers concerns!!  :angry:

Drop The Doc a PM as I know he has people up your way who might be able to help you out  :smiley:

How long have you had the map on the car? Do they have money back guarantee if you are not happy??

Seems like very poor customer service and a very dismissive attitude  :angry:

If it were me I wouldn't leave it at that, I'd go back to them and demand further investigation as has been suggested.

I'll see what next week brings

What awful customer care, I was torn between Revo and APR when I had my car mapped as I didn't fancy taking any chances on a 'smaller' outfit should there be any issues for the sake of a few hundred quid.

Good luck, I hope you can find a satisfactory outcome.
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 12 July 2013, 16:13
I think I may try and persevere until APR have finalised their cr170 map.
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Buck on 12 July 2013, 19:15
Whatever you do, don't give in.

They've done something with the map that has left your car in less than good condition - you taking the Leon for the weekend shows this.

Ring them Monday and explain your concerns (I find it helps me to write these down so I don't miss anything or not get my point across clearly and accurately)

Ask them what they propose to do to make you a "happy customer" and if they are not prepared to adjust the map then get them to return it to stock so at least it is driveable and not with the issues you describe.


All that can what until Monday - Enjoy your weekend

Thank you very much for the offer.
I'm on holiday until Monday night so will see how I get on with Sedox Tuesday and if not I may ring you.
Wish I'd knew about you before blowing £400.
That's what mappings all about helpful people and obviously from you great customer service.
Top man :grin:

I disconnected the battery on my car on Friday morning before I left thinking its worth a try.
Anyway I returned today and reconnected the battery and the cars performance is back and the boost leak noise has gone!!
Anyone any ideas why?
The only difference is the outside temp is down to 21 degrees today (28 degrees last week)
The only other thing is the battery being disconnected.
Anyone any ideas

Post by: Raffe on 15 July 2013, 14:58

It was never 28 degrees in Scotland  :grin:

In all seriousness that sounds promising as it sounds as though its cleared some issues.

Ooh cheeky. :wink:
Yeah done just over 20 miles this afternoon and its back to normal.
This proves what I said about no boost leak but it seems strange why a battery reset would fix it.

Hi Mate,

Only just saw this reply due to your PM - a wee bit busy at the mo, please ask them to put the car back to standard protected if needs be as I dont really want to know whats in there ;-)

I have an engineer in Scotland soon, I'll do your map for free but you'd need to pay him £125 for travelling to you and doing the spanner side or come to me / us and I'll do the whole job FOC  :wink:
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 16 July 2013, 17:14
As it is the car still has the map on.
I'd rather not of went back the 180 mile round trip to flash it to standard.
As is the ecu is unlocked and was flashed through the eobd port.
I'd probably travel to you.

You'd need a very bright torch me thinks :grin:

Can you do it without me returning to standard?
Also when are we looking to do it?
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: The Doc on 18 July 2013, 13:54
Indeed,

Best case for my starting point is an original, stock healthy car, I also always like to work from the original file in a car rather than a "best, closest file" that I can get for a million and one reasons.

I'll talk so sedox if you don't mind and ask them if they will give me the original from your car if you don't want to go back or they won't put it back to original for you.

I may be able to work on your car via the OBD socket but I'd be very surprised if they have left the access to the ecu "unlocked" for anyone else to look at which means ECU out etc.
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 18 July 2013, 14:43
By all means if you want to talk to Sedox regarding its original file that's fine.
The ecu must be left open as they flashed several files back and forth.
They said if they flashed it to standard it would become locked again.
Looking forward to perfection.
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: The Doc on 18 July 2013, 16:19
FYI I'd love it to be locked again and standard...

If you flash 17122 files into it you can still put it back to standard.

Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 18 July 2013, 17:06
So what do I need to do?
I emailed Dave a Sedox lastnight telling him I wanted the car returned to its original standard software but haven't heard anything today.

Hi,

Got it, tried to call you back a few times but gut an answer message.

Is it on now?
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 25 July 2013, 15:03
Well just an update on this.
My car is sorted but it cost me to get it sorted.
What's was wrong with it?    SEDOX PERFORMANCE SOFTWARE.

After a long conversation with The Doc who was extremely helpful and knowledgable and was willing to map my car for free! It got me thinking.
As the Doc said previously the cr170 is not an easy car to map.
I needed my original stock file loaded on to the car so that Craig could remap my car.
Sedox were going to supply a newer version of standard map and not my original file. I felt this was totally unfair to expect Craig to try and map my car successfully from someone else's software, ie not good to start with.
I then contacted Revo who said they'd flash the car to stock first which they did and instantly the car was ultra quiet and drove perfect again, to the point that in most gears/revs it was quicker than before!!
I then had Revo stage 1 software loaded and the car has retained the quiet silky smooth performance it had standard only much much more powerful.
So its now cost me £784 on software for a stage 1 map which is now perfect.
I learnt the hard way.
If your mapping your car stick to someone who knows their stuff like Revo/APR and the Doc of course who ran a gtd and developed the software and knows what's what.
So if you want to enjoy some extra power without all the hassle I've had Avoid Sedox performance
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Raffe on 25 July 2013, 17:38
You get what you pay for, Revo are a market leader for good reason IMO.

Good end result.

Post by: Marshy on 25 July 2013, 18:05
Yeah happy now mate.
I wanted Revo originally but was guided by Dave at Sedox (PDT) on the mk5 forum.
I guess people have different standards and mine must be higher than happy Sedox performance customers.

Glad its sorted out marshy, whats the map like now, does the
Power arrive lower down the rev range now, is it smoother
Than stock,
Title: Re: Diesel knock harsh noise since remap GTD 170
Post by: Marshy on 25 July 2013, 22:14
The power comes in lower down the revs and is as smooth if not smoother than standard.
The best way to describe it now is it drives like a turbo petrol car now.
I once had a leon mk2 tfsi 200 bhp and I'd say it drives like that but quicker.
I'm just pleased its sorted and as I knew my car is healthy.
I now remember why I bought the car. Silky smooth with great economy.
Thanks for the support guys and a big thank you to The Doc

Post by: Marshy on 20 August 2013, 08:36
When I got Revo it was on 20% discount so it was £399 all in.
Not sure if the discount is still on.
Generic map but its very good.
