So I got four injectors reconditioned by an expert and they have been fitted to the car and the car is still the same. The mechanic is now talking about there is lower compression on cylinders 1 and 2 than 3 on 4 with the new injectors in and he is talking about the various possible causes of that. He said on early FSI engines like this you cannot switch of the misfire counter so that is still producing the error codes. He said his most valued employee a younger guy who is a mechanic has done a lot of tests on the car. They are suggesting to take the engine apart and to clean various valves associated with the cylinders but they are worried they might find Bore Score in Cylinders 1 and 2 also. This will cost a lot of money to take the engine apart right down to cylinders.
I thought that Bore Score in cylinders could be viewed by sticking a Bore Scope through the spark plug holes. Is this possible please on an Audi A2 FSI Petrol 1.6 or do you have to take the engine out. Perhaps the younger mechanic has done this but what if he hasn't! If there is bore score in cylinder 1 and 2 is there any simple fix here like putting thicker oil in like you would on a Porsche or is this 1.6 FSI engine a poor respondent on that old trick. Plus I saw an article which said you cannot get larger pistons for the Audi 1.6 FSI which makes a re bore almost impossible.
