Engine: TD: C30 1.6 TD limp mode issues Map or mas Sensor - Help???

[Greenlider23]

Hi everyone,
I'm having some issues with my C30 1.6 diesel, usuall engine warning light on, so had it put on the diagnostic and it came up DPF issue, since then I had it carbon cleaned and it semmed fine for a very short time and the engine warning light came back on. A guy who looked at it said he was familiar with the issue and recommended changing the MAP sensor, so I am trying to find its location to replace. Anybody had the same issue and was it resolved by renewing the sensor, because I've heard it could also be the boost MAS Sensor aswell. It is struggling with power, seems like its in a mild limp mode. Any clues? Would appreciate any assistance on the matter Thanks

Thanks, I will start with the filter 👍

I've had a similar issue and my local garage identified it with what he called a 'pouch' that holds the fluid that is injected into the exhaust system. It is contained in a box below the boot. Apparently if the pouch needs to be replaced, it costs over £400. Is there a 'pattern' version that works and costs a more sensible amount?

fuel filter. check eloys fluid level.. clean the sensors before replaceing. have code read before doing any thing with vida if possible as some generic code readers dont do well with volvos

Thanks. It turned out that the reservoir was empty so all now sorted. Although its not a Volvo dealer they have a Zenith reader that costs over £7k and seems to give reasonably good diagnosis plus he's a good mechanic.

glad you got sorted these kind of problem can be difficult to sort without good equipment
