Title: GTI Turbo misfire issues
Post by: zorg86 on 23 September 2010, 20:46
Hi people

New member here problems with my car, basically change plugs etc due to misfire not solved, bought new coil tried each one not solved.

Took car into garage today showing cylinder 3 missing just wondering if this could be the igniton amplifier module at fault?

As I have been reading and the garage can't find out and are saying it may need full re wire and ecu.

Any help or advice appreciated.

A full rewire is a little extreme! Take it to a VW specialist mate. What is the engine code?

AGU engine?

 99% the ignition amp has failed  :wink:

Yes AGU engine I thought that when the said the wiring and the ECU I just font want get raped, thing is my car is in garage still under 'investigation' should I just ring them and tell them I done research or ask for car back?

I would for sure! it is a 5min job to fit!  :wink:

You can get one here :

Not sure on the quality? Personally i would get a genuine one.

Im 99.9% sure that is the fault - though dont blame me if its not!!

Please let us know the outcome :afro:

I will do and I'll ring the garage first thing see what they have say. But question is should I request for car back and yeah I know where the part is (am I correct in saying it the module on side of airbox) and I'll also be calling my local euro car parts

Yeah i would not let them work on my car after that advice!!  :sad:

Yes get the car back and replace the part yourself - do it out side the garage all you need is a screwdriver  :laugh:


Yes its on the air box  :wink:

This must be the month for which ignition amps go on the gr8 AGU engine,Happened on mine,just over 100 quid for the part.

I would say Ignition Amplifier, Mine went last month and it took the garage a while to find out the fault

Right an update, got te part  rung the garage, went with the part they said they don't think it's that as they took wires off tried ecu cylinder 3 still said misfire. So I asked them put the new part on he said he got put wires back on car then will do it and ring me.

Who reckons I'm gonna get fibbed off by these guys? Or who reckons they might be right?

What I thought he just made no sense to me I said to them put the wires back on and then put the new ignition amp on and call me. I have a very bad feeling they are going ring and say no that ain't worked

Then I'm just gonna say give me the car back

The problem is if they do that - it may have been the ignition amp at fault and they have now caused a fault on the ecu / wiring which wasn't there before - it would be a nightmare to fix as you dont know what they have done to it !  :angry:

They put it back together and said the ignition amp was at fault.

But have now tried a live feed from the ecu pos trigger and it is still misfiring now saying it's the ecu so basically they have f**ked the car on me by messing

Fook  :angry: :angry: :angry:

They can fit a new one F.O.C then.

Do you think they are to blame then? There saying ecu is going to have to be sent off. I'm fuming and don't really know where to turn

Yeah i think so - it is hard to prove though  :angry: :angry: :angry: :angry:

Tell them that as the amp was at fault and as they have admitted this there is NO WAY you are paying for the repair to the ECU!

Post by: zorg86 on 24 September 2010, 13:09
Suppose you may be right so taking the wires off can damage the ecu basically, and I will just have go see them I'm not going get my cat back any faster

Stick with it don't pay a thing for their incompetence !!

Keep us updated  :smiley:

Is there anyway to reset the ecu to hopefully pick back old settings or is it a case they just f**ked something up?

Hello to everyone who posted on my thread now an UPDATE!!!!

Got car back today all sorted so I'm a happy guy :)

Bit of a breakdown here the ecu had no live feed after by passing it to cylinder 3. So I got the ecu from the garage took it to Camco in Warrington on Friday they rung yesterday with nothing up with the ecu.
So the garage fitted and hey presto car works, we think camco must cleaned the terminals and possible reset software (which I think they have as I had a remap and car seems much slower gutted)

But also had the new ignition amp fitted and oil and filter change it runs better than before just slower but thanks guys for all your help I think it had a problem with ignition amp also but all I can say is I am happy now hav car back cheers for the help...

would a 51 plate have this ign amp?

i ask as my 1.8t has a very slight miss on idle never bothered me but now im selling it soon i best get it sorted, i was going to go down the usual coil pack route and buy one and try on each cylinder till sorts it, i know they are common as hell, i will plug my code reader in and see what comes up but the cars been with my mum for the last 6 months getting it back next week hopefully.

i seem to remember bypassing the n249 valve or something like that the other year, anyway to test coilpacks or ign amp with a meter etc?

Doubt it which engine code? Im sure yours will be AUM which wont have an amp - AGU  have them  :smiley:

Boost leak  :undecided:
