Peugeot 207 (2010) Engine fault?

[mj3]

I've been having some difficulties with my Peugeot 207 (2010) 1.4l

About 5 months ago having engine trouble. Wouldn't even turn over. Anti pollution warning on dash and engine light on the monitor. Intermittently prior to this I was also getting electrical fault 'battery charge or electrical supply faulty', but it ran fine.

Had it towed to Peugeot franchise repairs who reported they found battery acid leak which has got into the harness and messed with the electrics. Had a new one fitted along with new fuel injectors to replace ones I was told were faulty. New spark plugs. All this seemed to fix the engine problems. It started and ran OK, though I felt it lacked the acceleration and power it once had. The electrical fault warning would keep coming up "battery charge or electrical supply faulty". Peugeot reckoned the alternator might be shorting and setting of the sensor, but as the car was running fine, and battery was charging fine, I left it. 

Today tried to turn the ignition and it just turns over, starts (weakly) for a few seconds then dies out. No error messages on the dash.

Main questions I would like answered:

1. What's the likely cause of this? To me it seems as though its fuel delivery related. Cant think its the fuel injectors though as just had them replaced...? Maybe the fuel pump?

2. Am I looking at 2 separate faults here i.e. electrical (maybe alternator) and engine related (i.e. fuel delivery) or could they be linked by single issue?

3. I'm loathed to have it towed to the garage (£100) for diagnostics (£50+). Especially as I'm not convinced the original trip to Peugeot got to the root cause of the issues, as a similar thing has now happened again, and never felt it got back to full power. Has anyone had any experience with Click Mechanic?

Thanks for reading. All thoughts appreciated.

You should take it back to the dealership that carried out the repairs in the first instance.....

Nothing more...their repairs should be warrantied..

What was replaced ?

Just the battery ?

Sounds like it will need new engine harness/wiring loom

Why was it not replaced at the first instance? Did you decline the work ?

Did they repair any damaged wiring

Can this be moved to the ''Next garage to try'' section !

" they found battery acid leak which has got into the harness "

Hi - thanks for all your replies. I've dug the paperwork from Peugeot out of the glovebox.

"Found no signal from engine speed sensor - found sensor snapped off, replaced but still not starting. Checked spark ignition coil found poor - replaced spark plugs. Still not starting. Sent injectors away for investigation - found faulty. Replaced injectors. Vehicle now starts but still fault logged. Stripped harness to find corrosion on wiring on engine harness. Replaced harness and wiring loom. Running issues resolved."

He thought it was an old battery that had leaked, and then had been replaced previously. He couldn't find any issue (i.e. leak, not holding charge) with the one in it at the moment. I bought the car 2 years ago and had no problems until this. I'm still sceptical that +2 year old battery acid was to blame.

"Vehicle requires a new alternator and battery ECU" - I declined this at the time as the money was getting silly, and the car was functioning OK (besides the error message). I was advised it was likely a short in the alternator and the battery seemed to be charging and holding charge well - so no actual functional impact on the car.

To add confusion I just went out to the car to get the paperwork. Tried the key in ignition and first time choked and died but all remaining attempts started and engine maintained up to 3000rpm. Noted a 'pause' in the revs as I was pushing the accelerator, but engine kept going throughout.

Any further ideas to guide me?

Too many different things it could be
You need to take it to a good independent garage.
Where are you?
Maybe someone on here could recommend a good garage to you.

That's one unlucky car....... snapped off crank sensor, 4x faulty injectors, damaged loom, faulty alternator, ecu....

As above, take it to a good garage that knows what they are doing, and they should be able to get to the root of the problem.

I've had two cases of battery acid causing problems first was a golf where the acid had eaten the loom under the battery box resulting in a non start situation,second was acid falling onto a clutch cable making a plastic part become brittle and hence shattering,took three cables before i worked out the cause thinking just a bad design.

I'm in Rainham, Essex. Not far from you it seems! Any suggestions for a decent independent garage round here? Especially if they specialise in Peugeots...

I wonder where the owner got with this?
I also wonder if the alternator was tested for overcharging. Acid leakage from a battery can be caused by a faulty , over charging alternator and give many other
electrical problems.

might have been a blessing ,probably you would be correcting past repair attempts ,
