• Random question: our car went in for a service the other day and first trip after it came back Mrs Sparky said it was spluttering and juddering and the engine warning light came on.

    It’s gone back to the garage today and they’ve told her “corroded coil and plugs” and quoted £500. Not a single issue before it went to the garage.

    I’m going to call at lunch. What do you guys think? Anything I should be asking? Sounds dodgy to me. Plugs are a few quid, right?

  • Sounds like bollocks to me. Spark plugs can't corrode to any significant degree, or at least they shouldn't in normal use. Coil packs on modern cars are covered in plastic and the only bit to corrode would be the terminals, which could be cleaned up easily if necessary. Sounds like BS to me. Ask them what the OBDII fault codes were.

    P.S. Plugs are indeed cheap. Coil packs can be quite pricey, especially as some cars have four separate coils but bundled together in a single pack, so you have to replace all four.

  • Which garage? I've had positive experiences with Mersh Bros behind Bellingham station, so if it wasn't them wot buggered it, they might be able to help you out.
