Hi Yang...welcome to the Forum! Not sure what engine you have in your car as there are several different timing belt arrangements depending on the engine. I would imagine that if the timing belt drives the waterpump and the pump was replaced without replacing the cambelt and tensioners (unless they were relatively new at the time) then that was mistake number 1. Generally at 62000 miles/8 years on the original timing belt, if replacing the waterpump (assuming it is part of the cambelt arrangement) you would also replace the belt and tensioner due to the age/mileage...a false economy not to! Also, as parts have been disturbed during the stripdown/rebuild, then this can also lead to premature failure through slightly re-aligned components, belt tension (old belt), etc. Good luck with your quest...let us know how you get on with it. Cheers Trevor

HI Jason...welcome to the Club! What a fine selection of VWs...definitely a VAG man then? Look forward to seeing the Audi evolve over time, you'll have to keep us posted with the mods Good to have you onboard. Cheers, Trevor

Hi Phil...welcome to the Forum! I personally would go for the manual, with the sort of mixed driving you do, there wouldn't be much point in an autobox...different if it was all town driving...but thats just my personal preference Let us know how you get on with your decision. Cheers Trevor

perfume (or aftershave)

Hi Louis...welcome to the Club! There are various bolt ons available for the Q7 that will enhance it...sidesteps, etc. If you could post some piccies up of anything you do as we would love to see the before and after shots. Cheers, Trevor

I've moved your post into the Classic Audi section as someone may see it there who is more knowledgable about the Audi 100. Hope you get some responses soon

Great result all round !

That's a great mod, thanks for sharing with us. You certainly have done your research which is always good when evaluating a mod to see the gains

Hi Lloyd...welcome to the club! I would definitely take it back to the dealer who sold it to you if it was very recently and get them to resolve it...I'm sure it's not going to be too much but pretty bad if you have to foot the bill when you've only just bought it. Let us know how you get on Cheers Trevor

Easiest way to check is with a temperature gun and point it at various parts of the engine and cooling system as it sounds like a blockage or air lock somewhere in the system. When you have found the cool spot, thats where the blockage is and where its not circulating...may just need bleeding through or back-flushing the system. Another route to consider is to carry out a block test with a special tool that most garages have that measures combustion gas in the cooling system...it uses a fluid that changes colour if there is any combustion gas in the system...instant diagnosis!

Oh dear...not good but at least it's only a few days in so they would almost certainly be obligated to sort it free of charge. Hope it's not left too much of a sour taste at this early stage of Audi ownership?

Hi Dean...welcome to the Club! It doesn't sound too bad as it has service history and if it seems to be looked after quite well, the mileage is not bad for a diesel and they tend to go on for a lot more miles than than, so sounds quite good overall. Looking forward to seeing piccies of the car when you get it Cheers Trevor

Hi Gordon....welcome to the Forum! It sounds like there is an exhaust leak, especially as the system has been altered recently....check by getting a friend/wife/neighbour to put a rag over tailpipe(s) to seal the exhaust and you'll be able to hear where it is escaping from. Alternatively, it could be a split in one of the intercooler hoses that's making the noise. Let us know how you get on with it Cheers Trevor

I wouldn't necessarily replace the bearing if it doesn't need it but I would ensure you follow the torque sequence exactly as some of them (not sure if your model is too early) use a bearing which you have to tighten the hub nut to the first stage with the weight off the wheel then go for the final tighten when its on the ground to allow the bearing to completely centralise and load correctly.

Absolutely superb and still think all the mods are completely relevant and a great basis for any additional ones to build upon what's there. Not sure about the green laces though

Hi Eric...welcome to the Club! I believe the option was there when buying new and is selectable but if not, Audi do offer a Fixed Servicing plan which is not unreasonable cost wise...on par with paying up front I would say. https://www.audi.co.uk/owners-area/servicing-maintenance-mot/fixed-price-services.html#/fixPrice?id=4&serviceCode=SERMIN Cheers Trevor

Sounds like you've picked the ideal path for modding your S4 so far...would love to see some photos of the various stages if you get any time. Cheers Trevor

Hi Geoff...welcome to the Club! It sounds like one of the VAG emissions scandal rectification letters. Any chance you could post up a picture of it (without any personal details showing) so that we could see it? Cheers Trevor

Hi Harry....welcome to the Forum! If I were you I would replace the coolant pressure cap on the expansion bottle as this may be the problem if it is not holding pressure. Very cheap to sort and probably the best place to start. Let us know how you get on. Cheers Trevor

Hi Jamie...welcome to the Club! I think the EGR delete is a must but not sure the DPF is such a good idea with MOT testing, etc but if driven hard on the right sort of roads it shouldn't be too much of an issue. I don't know what other members think??? Let us know how you get on with it. Cheers Trevor

Was just about to post up a response say that it is spline but replacements seem to be hex. Glad you got them out as they can be a pig to remove, I usually put waterpump pliers on outside of them to help shift them if they don't budge. I'll let you get back to the job in hand! Cheers, Trevor

Welcome to the Forum! Modern engines do consume oil within the running in period which can be some length of time depending on how it is driven. To use some oil is not uncommon as long as it isn't producing clouds of blue smoke from the exhaust. Once the car reaches it's first service then sometimes the oil grade can be changed depending on how the engine has settled in. Easiest thing to do is just keep a regular eye on the level and maybe keep a log to ensure it isn't using excessive amounts Cheers Trevor

Have you got any pictures to post up so anyone who is interested can see them? Cheers
