    Default 2008 Pug 407 2.0 Diesel auto Sedan doing strange things

    I think I am cursed. I recently had a bunch of issues with our 2007 Pug 407 wagon after I stupidly incorrectly installed its battery after an overnight charge. Within days of having the wagon running beautifully, our 2008 407 sedan has decided to play silly buggers.

    The sedan has given us next to no issues until the last week. I recently installed a new battery in it (about a month ago). It had one of its usual services at the same time - new air filter, oil filter, cabin filter, diesel filter, oil change and new tyres.

    Late last week on every drive it would throw up all sorts of errors but continue to drive nicely, as it always has. In sequence - the radio would cut in and out, the LCD display would flash on and off in sequence with the radio playing up, we then get an air bag error on the centre LCD in the dash, abs error, esp error, rear parking sensor error, the errors eventually all disappear, the reverse sensors do not work and the radio seems to power off for a 1/4 sec and then comes back to life regularly.

    I have put the battery on the charger but the errors are the same the next day.

    Lexia isn't much help.

    Is my sedan possessed or am I just jinxed?

    Wife wants me to get rid of both Pugs and get a couple of "decent" cars. I think she liked our Audi's better. It doesn't help that the air cond is not working in both 407's.

    Help before I am forced to ditch both diesel 407's for something impractical like an Audi S4/RS4 and a Q5 for her.

    If your wife thinks an Audi is a great improvement, ie decent, I think she'll find that Mr Bosch electrifies both engines.

    I have seen this insane behaviour in Pugs, but so far not from a 407. It was caused by improper battery disconnection/reconnection, which unfortunately happened to you. If the code is really screwed, beyond Diagbox resets, a software reload (dealer, unfortunately) may do the trick.

    In addition to what seasink has posted -

    Have you checked the alternator output?

    A family member has just purchased a SQ5 Quatro. I can confirm it is beautiful car to drive and has blistering performance.

    After an extended drive, I can even overlook the fact it is a diesel.

    There nothing impractical about the SQ5 Quatro.

    Sounds like alternator over charging

    Looks like a BSI reset has fixed it.
    Armidillo and dimistyle like this.
