Fault Code P15A8

Post by Nipidge » Tue Feb 05, 2019 12:09 pm

Hi everyone, my cactus (Flair 110 Petrol) has acquired a fault - P15A8. A garage has run a diagnostics check on the problem and the fault relates to: W Phase Motor Current Sensor Circuit Malfunction.

The reason for the diagnostics check was that the engine light appeared on the speed screen in orange, and on the main centre screen it states engine fault contact dealer. I have also had a warning to say the oil pressure is low and sometimes the STOP sign illuminates and the car goes into limp mode and has to be stopped, left and restarted.

The mechanic said today it could be a problem with the camshaft and that one of the cogs may be misaligned or the oil sack in the middle of the cogs may be leaking.

This is the third problem this car has had, it's a 65 plate with just over 53,000.00 on the clock. It is serviced regularly without fail and driven sympathetically.

Has anyone else has this kind of problem and if so how was it rectified. The mechanic has warned if it's a new camshaft then a large bill of £1,500.00 could be possible.

If anyone has any help and advice then anything would be greatly welcomed.

There is a technnical service bulletin for P15A8 combined with low oil pressure.

Checks are given for :

• The condition of the strainer of the oil pump
• The state of the oil filter of the vacuum pump
• The state of the filters of the 2 variable distribution solenoid valves

With recommendations :

Replacement:
• Vacuum pump (if necessary)
• Timing belt
• Lower oil sump (Only sheet metal version)
• Oil filter
• The hollow screw of the turbocharger oil connector and its seals

Cleaning :
• Oil pump strainer (if necessary)
• Filters of 2 variable distribution solenoid valves (if necessary)

Hi littlejim,

Thank you so much for your help, I have managed to translate the document into English. It makes for interesting reading.

The car went into Citroen in September last year as there was a oil leak that was repaired under warranty. However, at the time this was done we had to have a new timing belt due to the oil spilling on to the belt, this we had to pay for. It sounds like this should have been picked up then by the Citroen garage.

The car is booked in tomorrow so hopefully should know more after that. I'll keep the forum informed in case someone has a similar issue.

Thank you again it's greatly appreciated.

Interesting to read that you had to have the timing belt changed due to oil spilling on it. I thought the timing belts on Puretech engines run in oil

My error, the auxiliary drive belt was replaced not the timing belt.

My citroen cactus Flair 65 plate has 51k on the clock. After warning light came on including warning to stop the car, the garage identified fault code P15A8 and warned that it was a major fault.
Needed to put in new oil pump. Electovlave and solenoid valve. Total cost over £1700.
Citroen aware of this problem as issued a service note . There was no warning that this fault was likely and nothing i could do to prevent it but it does seem to happen around the 50k mark. Be warned.

Thank you for warning us of this latest sensor code. I hope it doesn't come up on my Cactus screen, I have had enough of my deplorable and demoralising expensive car.

My car has just under 50,000 miles on the clock, and I just had a massive bill. The only warning I had was a generic 'Engine Fault' warning. I planned on taking the car to the garage at the weekend and so continued to drive. Later I got a 'stop' warning and was luckily right by a garage. It seems the car had run out of oil (it has a full service history and was last serviced 9 months ago) because the cylinder head expanding plugs had failed. This meant the timing belt failed and properly screwed up the engine. Because the timing belt is immersed in oil, it is complicated to change and water pump and lots of auxiliary work necessary too. Final bill: £1350!

My car has same issue and only 43000 on clock. Took to garage as car went into limp mode. They cleaned strainer and said it had stringy bits in strainer - it was then I found this. Started driving car and, although not in limp mode, engine fault light was on. My local garge then informed me there is a recall on my car - contacted Citreon and took to local garage and recal notice is for Bonnet Catch and button on steering wheel (all done foc). Spoke to garage with regards to the issue with this code and the fact stuff found in strainer and they admitted that Citroen are aware of this and have issued advisory!

They said if I had that issue the car would be fixed by Citreon. They have now advised me that I do have that issue and it was likely caused by the engine being "flushed" when I had oil change as this can make belt disintigrate. Spoke to garage that did oil change and they dont flush!!!!!!

Dealership are now saying that Citreon will cover cost of work if I can provide full service history - if not it will be 3.5K!

Have spoke to other garages and they are reporting other Citreon owners having the same issue. They also state this SHOULDN'T be happening in a car with 43000 on clock! This very much sounds like a design issue and it sound like I will have a battle to get the work covered!


Apart from "WHy dont you have a fulll service history?" Any thoughts? I might push this harder as it does sound like a design fault that could be costing owners a large sum as Citreon dont wish to pay for it!

I too have a 65 plate Cactus with the P15A8 code fault. My mechanic has quoted £5,400 to repair as it needs a new engine and all the parts the oil goes through to be replaced. This is more than the car is worth.
Has anyone on here contacted Citroen about this fault?
Has anyone else been quoted such a high amount and if so what did you do?
Thank you in advance of any advice
