Thought I would start a bit of a build thread to document some of the mods made to the car. Maybe somebody might find something useful . After owning a Passat for 7.5 years and making so many mods to it I wanted to get something a bit newer, And a new challenge. Looking at the new shape Passats I didn't really need a car as big as a new shape B6 / B7. I wanted to stick to a diesel estate but wanted something that I could tweak to some bigger numbers. My 1.9 Passat TDI was making 207 bhp and 345 Lb/ft of torque. The B8 Audi A4 seemed more like the size of car I was looking for being pretty much the same size as A B5.5 Passat with several Quattro options. As I found with the Passat that getting the power down was an issue with only just over 200bhp. So after much looking bought an Audi A4 3.0 TDI Avant Quattro Avant . Its an 08 plate so one of the first B8 models. Went for a manual as on the B7 they had a 240mm clutch on the B8 it has a twin plate 228mm clutch arrangement so hopefully no issues when tweaking it.The engines in these have the latest 3rd gen 2260 Garret turbo's which means better performance and fuel economy. It's an SE with S-line leather/alcantara interior and the optional S line 18 inch 5 spoke alloys. Also came with a factory fit removeable tow bar. VAG-COM showed a duff glow plug on number 2 so changed that, and the fuel cap solenoid which is a common problem was changed. Fuel cap was permanently open before. Also showed up on a VAG-COM check of the car. Pictures aren't very good and the car needed a clean but you get the idea. It's pretty much the same size as the Passat, the mat I used to have in the boot of the Passat fitted almost exactly on the boot in the A4.Where the screen slopes at the back is where you lose space but I rarely ever loaded the boot that high. Made a few mods with VCDS / vag-com Enabled driving school mode so speed appears in main display, you can turn this on and off in a menu option now. Enabled the battery monitor The lap timer functionality Altered the splash screen on the stereo, Normally has no logo, You can have an S logo or RS. Decided to go RS. Enabled the dial sweep, click on the picture. Bought an oil dipstick as the car doesn't come with one. Has the tube with a bung in it. It has a sensor and displays oil level on the display in the car but I wanted a dipstick just to check, Only £8 from the stealers. Fitted the R8 oil filler cap from the Passat. Enabled the dipping rear view mirrors when you select reverse, flashing brake lights when you brake heavily and a few other bits and pieces. Ordered a set of Team dynamics Pro race 1.2 in silver 17 * 7.5 Wheel Range . Wanted some lightweight wheels and couldn't find anything OE in17 that I liked. I know most people would fit 18's or 19's but I like to stop with smaller wheel sizes as tyre prices for quality tyres are so much cheaper. Will be getting 235 /45 /17 Goodyear Eagle F1 Assymetric 2's about £110 each fitted. Thats plenty of rubber on the road and a 45 tyre sidewall will help the ride quality. Spare wheel has gone and replaced it with a compressor and bootle of gloop,Bought off Ebay for £20. Will be selling the spare wheel as these seem to be in demand and going for £90-100 Removing the spare wheel, jack , and the part of the tow bar that is removeable that was sitting in the boot has lost nearly 40Kg off the weight in the car.Also made quite a bit of space for stuff when we go away in the car. Spare wheel well houses the battery and sub for the stereo. Picked up a bargain off Ebay with some uprated brakes. The car currently has 320 *30mm vented discs at the front and 300 * 12mm solid discs at the back. The calipers on my car are the same as an S4 but the caliper carriers are a silly price something like £170 each so to buy 4 S4 carriers would be nearly £700. Bought this lot off Ebay, complete brake set off an S5. They are off an S5 but are identical to whats fitted to an S4. These are 345 * 30 vented front and 330 * 22mm vented rear and luckily enough fit under 17 inch wheels with a few mm to spare. Before I bought them had a look around at the price of brake parts and couldn't believe some of the prices . Ordered some new Pagid front discs at a silly £28.19 each, they weigh 10.5Kg each so £5 of that must be postage. AUDI A4 S4 QUATTRO 2.0 TFSI 07-13 Pagid 54602 Front 345mm Vented Brake Disc | eBay And a set of Mintex pads FOR £40 MINTEX FRONT BRAKE PAD SET AUDI A4 2007- MDB2934 | eBay The rears discs and pads I got are good so will be going on the car as is. Weight wise the front setup is about 1.5Kg heavier than what I have now , at the rear it's more like 2.5 kg each side. I will sell the original front calipers/ carriers discs and pads off my car but think I will keep my original rear calipers just in case I have issues with the silly electromechanical handbrake mechanism.
