Mk4 Golf TDI 150 - Bump, Smoke, Powerloss (serious) HELP

**utilityplayer** · 19-06-2008,07:40 PM

Sorry if this has already been posted somewhere on the site but i'm having a bad night, on the motorway on the way home tonight my golf lurched, there was a bang and a bump a belch of black cloud in my rear view mirror and a loss of power. I nursed it home and it was performing like a normal car, no turbo whine, no power really and revving upto 3k but dramatically reduced pull - What has happened???!?!?

Is it a fatal turbo loss, a split hose, injectors, clutch?? Please please could someone offer help and advice - thanks a million.

Have you tried it again since?

**utilityplayer** · 19-06-2008,07:59 PM

Not yet, turned it on on my drive and revved it and there was no horrible noise but afraid to take it our again, don't want to damage it further if it is a problem.

Any whistling noises?

No whistling and now it bunny hops

Hi m8

The Symptoms you describe maybe point to the (MAF) Mass Air-Flow Sensor being dirty & need cleaning or possibly replacing.

Alright mate i have the same car and the exact same thing happened. I thought id bust the turbo and feared the worst but it ended up the turbo pipe had spliy at the clip and it only took 20 quid to fix. I had the bad noise and black smoke

Can't quite remember who posted, either Cracker or BigCol, but if you think your MAF is knackered and reckon cleaning it will help, you are wrong. Attempting to clean it will guarantee that it's knackered, so save yourself the bother, quote unquote, more or less...

one of your turbo boost pipes has ptrobs come off, my mate had exactly the same problem on his golf gt tdi 150, on his the clip that holds the pipe on had broke and cost him 40p to buy!

I have a TDI130 and the same thing happened to me whilst on holiday, two garages would not look at it so i drove it home. The local garage found it to ba a split hose (under warranty). Lots of smoke and would not exceed 60 mph.
