hey all, got a mk5 2.0 TDI and the turbo went this morning? Anyone no where i can get the turbo for a good price, or where i can get it fixed for a good price, preferably in the midlands, im in coventry.
Thanks.
-
Assuming it's out of warranty, Stealth Racing in Southam or RSD in Banbury. How do you know/who told you its your turbo gone?
-
sounds bad :S what happened?
-
well the AA guy rekons its the turbo thats gone.
it works , for bout 10miles then stops, leavin us with a top speed of about 60mph, when i turn it off leave it for a bit, then it works again for another 10miles or so then the proble re-occurs, the engines slightly louder then before, but not drastically.
Any idea how much im goin to have to fork out?
-
ALOT :cry: :cry:
-
Typical AA man response. If it is the turbo expect to pay around £700 in parts and 3-4 hours labour.. but you should get a second opinion. Vince at stealth racing will take a quick look for you but if it was me, VW would be my first port of call (the £70 diagnostic inspection would be well worth it)
-
lol joe, really fooking helpful!
is that limp home mode cutting in then? did the aa guy run diagnostics on it?
just wait for T_T to bowl along with some knowledge!
You could potentially get a used turbo from a spare parts company... I used to use combellacks in cornwall quite a bit, may save a few bob...
-
Won't be that much, You'll get a turbo on an exchange basis for around £350-£400 quid, If your handy with spanners you could do it yourself in a couple of hours.
-

couldn't agree more...
I had aa out 3x before they managed to diagnose a faulty MAF/throttle pos sensor which Seat managed to diagnose in what, 10mins?
-
just spoke to stealth racing, really helpful, they said it sounds like its goin into the LIMP mode.
Its goin into VW 2morro (listers nuneaton) so they can diagnostic check it, although im thinkin of takin it to RSD as they'll do the check for free, where as VW will probably charge.
-
vw will definitely charge, Danny down at RSD certainly knows his stuff.. i've never had to talk mk5's with him though!
Limp mode is certainly a possibility, now you just need to find out why its doing that. (AA guys although they have the diag software, they don't all know how to read the info)

Ha ha. Turbos arn't really my strong area - other than they spin very fookin fast - about 160,000 to 180,000rpm !!! :shocked:
But Toph is spot on - take it to a VW garage, and get a full "on the fly" diagnostics done - with particular regard to "requested turbo boost" vs "actual turbo boost". Or if the OP knows someone with VAG-COM, this can also do this.
Do the latest TDIs still use the VNTs, or variable pitch blades?, because these can sieze and go south.
And don't bother with the AA/RAC etc. They are only useful for supplying new batteries at the roadside at rip-off prices. :shocked: Anything more complicated than changing a lightbulb, and they are fooked! :rolleyes:
-
some specialists in my opinion are better than the dealers. the bigger and busier the dealer is, usually the better as they come across all manner of problems more frequently than say one in the middle of nowhere

wipers?

I fully agree. However, no matter how "small" a dealer may be, they are always better at diagnosis than AA/RAC. :wink:

No you pillock! :rolleyes: :grin:
The actual blades on the turbo are able to alter their "angle of attack" in the air flow. This makes the turbo very efficient at low air speeds (low revs), yet minimises resistance to airflow at higher air speeds. It is usually just the blades driven by the exhaust gases which can do this - but because they are immediately after the "big bang" they are not only subjected to some seriously hot temperatures, but also any "crap", such as burnt oil, or diesel soot can coke up the mechanism, and cause it to seize. But I can't remember which position they seize at? :undecided:
-
And another thought!
Has anyone checked the fuel supply, as maybe the fuel filter is blocked or contaminated?
-
k i'll check my wiper blades and report back :grin:

Don't forget to "park" them in the proper position! :tongue:
-
parked wipers and bent blades, got ya :rolleyes:

Could simply be the acuator arm or vanos vains sticking. Quite common if innerads are all carbon incrusted.
-
I very much doubt its a mechanical failure with the turbo. If the turbo has thrown a blade, it wouldnt work for 10 mins and then die.If somethings come off it wont work period.
Sounds more like some kinda sensor failure causing the car to go into limp home mode.
Im sure it wont be as bad as "MR No it All" AA spare part in yellow Uniform says.
Do report for us after your visit to the dealer. :smiley:

Vanos is BMWs name for its variable inlet cam timing. But I get your drift. :wink:
BTW, I am liking your LEDs in the headlamps - got any more info? :smiley:

Not really. It is extremely rare for a turbo to "throw a blade" - if they ever do, then the turbo would suffer catastrophic failure, and the damage would be very visible.
But it is fairly common for the VNT turbos to seize up their VNT mechanisms. This wouldn't and/or shouldn't be apparant or noticeable when starting from cold, as you should only use the engine gently whilst cold. Only after the engine has reached normal operating temperature, will you start to boot it and give it some beans - and this is when the VNT will be at its most "active". The VNT mechanism works along the same lines as any other actuator, in that the ECU instructs it to "work", and after the item has "worked", a signal is sent back to the ECU to confirm that it is working OK. If the ECU doesnt get the "I'm working fine command", that is when the ECU can then change to "limp home mode". :nerd:

Yup, that too.

Agreed. I never trust those types. :rolleyes:

Yup, we need to know! :tongue:

saw this a while ago, explains a lot.

Anything the AA/RAC say I would take with a pinch of salt, my dads Passat TDI broke down once and that went pretty much into limp mode...the turbo wasnt coming in at all and the guy said prepare yourself for a big bill as your intercooler is foooked. Turned out it was a split pipe.
-
I had a split pipe on my 04 reg 150bhp PD GTI, which gave a huge performance hit
Stick your head under and have a poke would be my advice
