Hi,
Hope someone can help.
Golf MK5 GT Tdi 2004.
Tonight, I was driving my Golf and on a straight bit of road accelerated quickly. Once reaching around 50-60mph, heard a very loud bang (may have been from left-hand side). The car then lost acceleration and I stopped at a set of traffic lights with the engine ticking over. The car was spluttering for the next 20 yards with hardly any acceleration at all. There was a lot of smoke from the rear. There are no engine management lights on. I switched the engine off then on again. There was a brief, unusual smell inside the car when I started revving the car. The engine splutters badly and the rev counter is erratic, not reaching very high revs.
The car idles as it did before the loud bang.
I called the RAC and the mechanic noticed that the mass air flow hose and loose and virtually detached. He re-secured this but no improvement when the accelerator pedal was pressed - still the very bad misfiring and awful revs.
The car has been re-mapped in the past - around 4 years ago.
The car has experienced some lumpy idling/slight misfire in recent past which improved after regular use of Shell V-Power Nitro.
The car has had a replacement turbo in the past about 3 years ago (by Awesome Gti). At lot of other work was done at the same time.
The car is no longer drivable and has been towed to a nearby garage.
Any advice would be greatly appreciated.
Thanks.
