I'm experiencing a judder between 2200 and 2700rpm (roughly). It occurs on light throttle and is most noticeable at motorway speeds (70-80 mph).

It feels like the car slows down, then speeds up again slightly and sometimes it judders in waves, which always occurs at about 2500rpm. It still does it when the cruise control is engaged, but not as badly. This is probably due to the ECU counteracting the loss in power by adding more fuel and 'smoothing out' the problem.

It's done nearly 70k miles and has recently had a new turbo fitted (old one went blew a seal and dumped oil out of the exhaust) and the garage who changed the turbo nd fitted a new exhaust, said that they had fitted a new EGR valve, but I'm not 100% sure if this was done. It has also had a custom remap, but this was fine before the turbo went pop.

I've tried cleaning the MAF with Isopropanol, which didn't cure it, but the hesitation feels almost like a MAF fault, as if it is telling the ECU that there is more air getting in than actually is and less fuel is consequently injected.

Anyone got any suggestions for other potential causes?

Citroen UK have an excellent warranty offer on until 18th August, called Citroen Advantage.

Any Citroen up to three years old can have its warranty extended by 1 year for only £179. Normal cost £450. Seems like a no-brainer to me, so I have signed up for our C8.

We had a mailing from a dealer (not our regular one) about it, who are also offering to pay double this premium back to us if we 'change' our car at their garage. Makes the possible C6 slightly more realistic. Read more

I recently bought an Audi S4 avant 2001(6 days ag0), one owner from an independant Audi specialist . The car was HPI clear and no obvious problems.

I polished the car at the weekend and noticed that there were "rust pimples" coming through on the bottoms of all four doors and also the two rear wings.

I took the car to a VAG approved bodyshop who tested the paintwork with an Elcometer and the measures were fine. However, the Manager was sure that the car had had paintwork on it as the car "was to clean" for a 5 year old car with 49k on clock (Surely that is no reason to say that a car has had work undertaken?). Therefore, the car would not be covered by Audi's 12 year Anti Corrosion Warranty.

Am I within my rights to give the car back and ask for a refund? I paid top money for the car as the car looked mint and was from a leading independant.

Or should I be taking this up with Audi UK? Read more

Now that all you kind people have sorted out the best way for Martyminx to park in London, does anyone have any good advice regarding long term parking at, or in the vicinity of, Bournemouth Airport for a week at the end of this month please.

All serious suggestions would be very welcome, thank you.
