Today I was driving and over taking before pulling into a single lane and the car sort of stopped pulling at around 4,000. It was like it had lost boost. It then happened later once again in town, again at 4k. I have brought new plugs today (before any of this today happened) and changed them. Also done the air filter and fuel filter, all which were only 7 months old anyway.
Looking at the coilpacks, there are 3 different brands fitted!
1 Bosch (fitted in April), two are BREN branded (dated 2008) and the other is AG VW, dated 2007.
I'm guessing this mix match can't be good, any idea for best value and most reliable coil packs can be purchased from? I think it's best I will replace all 4 just to make sure. My new intercooler pipes should be here tomorrow and I'm going to check how secure the TIP is too. The DV works just fine which is good.
