That's true enough Brad-B5 .... at least you know what parts have gone in there over time.

Great news Brad-B5 (well for the car, not your wallet) and glad it's all tip-top again.

It could be temperature related....I returned to my car the other day, got in and immediately jumped back out! The interior temperature was off the scale so could quite possibly be extremely high temperatures causing a glitch

I would also have a good look at the spark plugs because these will show up whether the cylinders are running lean or rich and also which ones are likely to have experience detonation.

Strange one...sounds like a tyre delaminating but you would get a judder as well

Sounds like the instrument panel going faulty if both gauges are playing up.

Hi Jay....is there any juddering associated with the thumping sound? Are there any other symptoms or is it just the noise?

Sometimes the wiring going to the temperature sensor breaks just by the connector so worth checking that out before replacing the sensor

Hi Ian...I would say that the clutch or DMF, or both are on their way out but certainly worth another opinion through a test drive to confirm before shelling out good money

Hi John, sorry to hear you've had problems that early, however, it does sound like a one-off and maybe worth persevering with it. However, I would also get something in writing that if the same fault occurs again then you can reject the car based on a persistent unsolvable running fault (maybe?) Let us know how you get on with it

Hi John Gareth is right in his diagnosis about the head gasket but I would strongly recommend they carry out a Cylinder Leakage Test (using compressed air through a gauge hooked up to the cylinder (where the spark plug) to introduce air into the cylinder). The idea is that when you introduce compressed air into the cylinder, if it is head gasket blowing between cylinders then you will lose pressure, if it is wear in the bores/rings then the air will escape into the crankcase and you will hear it through the oil filler cap, if it is escaping through the valves then the air will either come out of the exhaust or inlet manifold, if head gasket through the coolant then you will get bubbles in the coolant tank. Simple test and non-evasive. If they don't have one of these bits of kit or don't know how to use it then take is somewhere that does, you'll save yourself a fortune on wasted labour & parts. Compression may also be down due to quality of oil...e.g. washdown due to excessive fuel or weak spark. If the oil smells of fuel then it is washed down and needs replacing urgently.

Not sure Bradley....maybe I can promote it through Facebook, etc if we need to bump the numbers up a bit?

okay...Wolverine?

Hi Chris....welcome to the Forum What a superb car....and a fine collection of previous ones :-)

Hi Mark....welcome to the Forum Maybe best to post your question seperately into the A4 section of this Forum...hopefully get some responses there

Hi Kevin....welcome to the Forum

Hi Richie....welcome to the Forum

Hi....and welcome to the Forum

Stay cool Brad....it's too hot out there

Hi Miguel....welcome to the Forum Good to have you onboard Cheers, Trevor

Hi Gary I would also replace the dual mass flywheel while you are in there. Albeit, there is a run-out measurement on the total movement from original but I would ask myself, do I want to open it up again in the future to replace it then or do it whilst it is apart? Let us know how you get on with it Cheers Trevor

Cooking oil also works well to brighten the plastic

Awesome!!!

Don't know that one...any clues?

lol...the number plate gives it away....
