Gti engine knocking sounds a like a diesel!!
« on: 30 July 2008, 20:57 »
Was looking at a 2005 Gti yesterday and on start-up there was the much talked about diesel sounding engine but even once the engine warmed up it still had a loud diesel-like rumbling!! The car was running on 95octane petrol, would this have any effect?
I took it to a main dealer who said it sounded quite loud but said it was nothing to worry about as it was 'normal'
What should I do?
The car has warranty until november btw!!

Depends how much it sounds like a diesel. I have a mint 2005 GTI V and they are grumbly at the best of times on tickover.  Knocking in the truly technical sense would be bad though. 95 fuel makes them run like a dog but the performance is passable.  Try it and absolutely floor it before you decide. I highly recommend about 6000rpm in 3rd!! Good luck!

The car drive's perfect, power in every gear as it should have and never missed a beat but compared with my old 05 Gti it sounded like a complete pig!!
It only has 40k on it but it's due a service in 400 miles....

Make sure it's not just an upgraded air filter or exhaust making it sound different.  You're traiding in a 2005 GTI for a 2005 GTI???  If i could do it all again i'd save my money and get an edition 30 when the right one came along fella...

No mate, I had a 2005 Gti and had to sell it after christmas to buy a house and now I'm in a position to get another!!
It cost's too much to import ed 30's into Ireland anyway due to stupid import taxes!!

From what I remember of reading the manual, 95octane petrol will cause knocking noises to occur until the knocking sensor is activated, or something along those lines. No idea how long this would take.

I'd love an ed30 but high import taxes here in Ireland just make it too expensive to buy one!
Irish dealers never officially sold the ed30 afaik.
Some day.........

Took the car to a VW dealer in Northern Ireland (as UK warranty isn't covered in Rep. of Ireland!!) 2 weeks ago to get the knocking checked out. The mechanic said it didn't sound right, which I already knew.
Got the car back yesterday, They replaced the timing chain, pulley and camshaft (as thet rung a bolt on it)
The noise is now gone and the car is running perfect and sounds like a proper Gti!! Delighted......
