Turbo problem

[chrisvrscrx]

that's one sick puppy. I think you are going to get charged a surcharge as most turbos are recons and that is well beyond saving

I rang a few some said it did not matter what the condition was like some said it does some did not ask they just said I have a week to return it, so I won't tell them.

If I want a new one it will be about £500 + VAT a recon unit will be roughly £400 + VAT there was one recon for £360 all in.

I still don't know weather to go to a breakers.

The German ebay site is also good for Audi turbo's.

I missed the auction 2 days ago for a VNT17 'VA' i was watching.

It sold for £17.

You can generally get a PD130 turbo for under £100 from a private seller.

A brand new turbo for your 'AWX' engine just sold for £92 on UK ebay a couple of days ago.

Then there is no need to exchange your old turbo.

Got a turbo £250 from a breakers, I got it VAT free because I paid cash. I know it seems expensive but I needed one and couldn't wait for ebay auctions to finish, It came from an 2.0 Tdi A4 with 30,000 miles, all the part numbers match up ok.

Going to start putting the new turbo on tomorrow, and i've been doing some thinking about possible engine damage.... Am I right in thinking that bits of metal from the turbo couldn't get past the intercooler because of the way its made? I've been trying to serch for intercooler cross sectional diagrams, and the ones i've seen seem to suggest the metal would get trapped. Does this make sense???

Your help would be greatly appreciated.

Still havent found the problem, I was messing about earlier on with the EGR valve taking the vacum pipe off and when the engine had just been revved the EGR valve made a 'tink' noise as if it were working but if the engine was left to idle for a while the vacum was lost in the pipe and it no-longer made a 'tink' sound when the pipe was pulled off.
*Also i pulled the pipe off the round thing on top of the turbo (dunno what this is called) and the turbo whistle stopped!!! Is this strange??*




When the vacum pipe was pulled off the EGR valve the turbo seemed to spin up, I've checked all the pipes and cannot find anythink wrong.

On the plus side my dad is an AA recovery man and he is on the a course where there is about 20 AA patrol men on it so i'm going to drive down to see them because one of them must have a clue whats wrong, I'll report back to whst they said but if anyone has any more thoughts on what I just said please let me know,

Thanks,
Chris.

Hope you didn't do what i suspect you did i.e pull wastegate actuator vacuum pipe off and drove it?,this removes safe boost control and if limp mode doesn't engage soon enough it lets the turbo boost to destruction... please ensure its refitted before road testing with a replacement turbo as 2 failures in a row would be harsh! cheers simon

After looking at all the pipes on the top of the engine and not finding any holes, I nipped to my local (non ***********) garage. He put it on the ramp and the leak was coming from the 'S' pipe from the turbo to the intercooler (front O/S). Cause - after years of running, the earth strap had worn away the pipe causing the leak.

Got a new on from VW at £72! and tied back the cable to prevent it happening again. Fitted in 20 minutes for £10.

Drives much better now.

Hope this helps you locate your leaks.

No idea on the diagrams, but I have heard of catastrophic engine damage caused by shards of metal getting into the cylinders, so it can get past the intercooler. Those cases usually happen when the engine could not be stopped by stalling though.

What a job!! been on the car since 5pm its not 00:45 just come in. Well first thing I done was to jack one wheel up put the car in 5th and turned the engine manually..... The engine turned fine very smooth.

When I was asking about the intercooler I have heard of metal entering the engine and seriously damaging it.... anyway I got it on the ramps and looked into the bottom of the intercooler wwhere the air enters and flows up towards the engine...a and low an behold I found loads of bits of metal (by the way I still aint found any past the intercooler) this leads me to believe that the intercooler caught all the metal as only air is small enough to pass through. Although I have been informed it does still happen.

I'm going to flush the cooler out and refit it tomorrow. I had to remove the bumber to get the cooler out.

I will start it tomorrow.....wish me luck, I don't need any more bad luck!!

Just tried to start it... No joy the engine turns fine but does not fires. I'm thinking the fault codes need to be reset because its coming up STOP on the dash,

Any thoughts???


I may call the AA out as I know they can clear fault codes.
