bmw e 46 initial start issue 318 petrol

[Gazzer01278]

In short had the engine light was on for a month and the car drove fine. Took the car to a garage to the sort underlying issue. Weak fuel was the symptom identified and the fuel filter was changed. Then an issue with the fuel pump came up, so new filter and pump have been fitted as well as set of new plugs. However, the first set of bosch plugs made the car run bad causing the light to reappear I am told, the computer showed misfire and the plugs were changed for new ones. Now on initial start the car is not firing up straight away, but starts fine straight after. The car was driving fine previously with the light on and just seems a bit odd that this new problem has just occured . It was suggested to replace the leads as it starts straight away after the initial cold start, but I am no sure this well help. Any advice welcome.

Sounds like:

• The engine is an N42/46.

• The garage haven't got a clue what they're doing.

What year is it?

Could be an M43, fond off a cold start misfire in the early stages of head gasket failure.

The M43, not a bad old lump but as Herr Helix says, could be the start of OMG HGF.

But the car was driving fine with light on ,and weak fuel was the route taken the light would even disappear at times so this is a new problem that has come from something that's been worked on ?
