Fault Code PO 183

[old son]

My wife was driving my 2010 90hp diesel Multispace B9 today and the engine cut out. She managed to start it and drive to a friends. She tried to start it around 1 hour later and it wouldn't fire up. RAC man primed the fuel system and it started. She got home in it but said the engine was getting worse the longer she drove it.

A friend plugged in his diagnostic and code PO 183 showed. Fuel temperature circuit A high.

I've looked on Google and cant find anything specific about the code. The car has started about 3 times since its been back but I don't want to drive it until I have a least found something that could have caused this.

Can anybody advise on what I should check please?

Thanks. When I took a look this morning I moved the air intake to the airbox whilst the engine was running and the engine stopped. I refitted the intake nice and tight and I've used the car since a couple of times and it seems to be OK. Its been up to normal temperature, allowed to get cold and it seems to start and run as usual. Could a bad connection for the air pipe have caused this problem? I was wondering if the sensor noticed a difference in flow and hence adjusted what ever it adjusts which shut down the engine.

I don't know much about the B9 engines & ECU, but on the M59 a lot of trouble codes seem to be a bit misleading and only point you in the general direction of what's wrong. For example, I was getting a P code that suggested my EGR was faulty but it turned out to be the MAF.
Often the only way to get a more precise idea of where the problem lies is to use the official Citroen diagnostics, such as Diagbox and even then some judgement is often needed by looking at the various readings. You could buy a cheap OBD reader & connect it to the Torque app on a phone, do a trace of airflow, ambient air temp etc and see what you can find.

The car performed exactly as it should again last night so I'm going to take this as a very lucky fix and keep my fingers crossed. Thanks for your replies.

Good stuff!
Just noticed that your signature line says 'chipped', what did you have done?

I had one of those tuning boxes fitted which connects to the wiring loom and is easily removable if ever the car is sold. Mine was fitted by TDI, website https://tdi-tuning.com/

The car certainly pulls better but I see no improvement on economy, probably because I am enjoying the extra power!! lol
