    Sensor replacement

    Hi, Need some help. I’ve been told I need to replace the sensor as per the photo, top of engine just under bonnet nearest windscreen. What is it? Part number? How easy is it to fit it? Cheers, Paul.

    Turbo turns off?

    Hi, Ok, have a reoccurring problem, have owned the car since Dec ‘20. In the early days of ownership the turbo would cut out infrequently, reset it with a diagnostic toll and all ok again. But recently the problem has become much more frequently, every 2/3 days. No warning light on dash. I’ve...

    Coolant leak from Thermostat Housing

    Hi, I am losing coolant, topping up expansion tank every couple of days. Took it to garage today, they eventually said the thermostat housing was leaking. They said that to get to it meant taking off a lot of kit to get to it, quoted me 4 to 5 hours work, they said the part was approx £160...

    No Turbo

    So the turbo has cut out three times over the last couple of weeks, but only today on way home did I get the engine management light on! A few hours after the third time of no boost.

    No Turbo

    Not limp mode, just no boost. My garage used a decent diagnostic piece of kit (Snap- On) from what I could see, definitely not a cheap imitation. P2191 stated Richness Adjustment : Mixture Too Lean. Pedro - haven't checked the Turbo boost control solenoid valve, so will ring the second garage...

    No Turbo

    Next installment. It's been ok for 4 days, been careful to warm up engine before taking it over 2000rpm. But today, did the same and the turbo cut out whilst driving sedately and engine up to temperature. Difference today is, ambient temp 8 degrees and heavy/standing rain. ☹

    No Turbo

    Hi Pedro, thanks for all your help. Not very technically minded, so excuse my ignorance. All I know, is that both garages said the code(s) were related to 'mixture too lean'. The first garage was my local and the second a specialist independent Peugeot garage. The second garage had different...

    No Turbo

    The fuel pump was changed earlier this year by previous owner. I didn't note the code this time round, previous code was P2191, both showed mixture too lean.

    No Turbo

    I had a previous RCZ and it never had this problem. There’s obviously a fault/ intermittent fault somewhere, a sensor or some component is playing up. It could be a dozen or more things I guess. Cars used to be so simple......

    No Turbo

    Ok, next instalment. Took it to an independent Peugeot specialist garage, they hooked it up to their diagnostics, a different code to P2191, but similar ‘ lean mixture’. They took it for two test drives and couldn’t get there the turbo to cut out. So, very frustrating, as I’m no further forward...

    No Turbo

    I’ve recently purchased privately a 2013 petrol RCZ with very low mileage. Took it for its first long run, about an hour, I needed fuel , put standard unleaded petrol in it, parked it up for 4 hours, then headed home, very quickly the turbo cut out. Took it to my garage the next morning, the...

    No Turbo ?

    It’s a petrol, haven’t checked anything yet. Probably take it to my garage tomorrow morning, hook it up to check error codes, but weirdly nothing has shown on the dash.

    No Turbo ?

    Only owned my RCZ two days, bought privately, did all my research, it drove perfectly, tested it four times. Took it for a long run today, first hour was fine, then on way home, feels like no turbo, no boost, but no warning lights on dash. Any clues anybody?
