Porsche 996 - 11 fault codes inc P0305 and P1315

[Poze123]

Hi all

Been reading on here for an hour, but I would still appreciate any comments or further advice on my cars issues:

 

I get 11 faults plus of course a warning light on the dash. The previous owner removed the bulb and as it was my first 996, I wasn't aware to check the bulb came on when the key was originally inserted.

 

So I have these codes from my Durametric:

 

P0300-MISFIRE DAMAGING CAT

 

P0306-CYLINDER 6 MISFIRE DAMAGING TO CAT CONV

P0304-CYLINDER 4 MISFIRE DAMAGING TO CAT CONV

P0305-CYLINDER 5 MISFIRE DAMAGING TO CAT CONV

 

P1319-MISFIRE EMISSIONS RELATED

P1316-CYL 1 MISFIRE EMISSIONS REL 

P1318--CYL 6 MISFIRE EMISISIONS REL

P1317-CYL 5 MISFIRE EMISSIONS REL

P1315 - Cyl 3 MISFIRE EMISSIONS REL

P1313 - CYL 1 MISFIRE EMISSIONS REL

P1340-CAMSHAFT POSITION WITH RESPECT TO CRANKSHAFT BANK 1 EXCEEDS LIMIT VALUE

P1531 Camshaft adjustement bank 1

 

Any advice welcome - I have seen a cheap set of Beru Coil packs I could purchase (always on a budget for cars as these are a hobby and come second to the family (kids) requirements). So anything I can do free or clean would be great. Id rather not buy Coil Packs, but if these could help and reduce my worries, i'll go for them! (plus the spark plugs).

 

Much appreciated,

Ps - 1999 Porsche 996, 3.4 Cabriolet. Owned for 3 years, well serviced on oil/fluids/brakes etc. Coil/Plugs never replaced by me, although I remember the Coil Packs were dated 2013. 

Car has done 97,000 miles.

 

Slight leak from the RMS. Otherwise it drives lovely, Idle is a little tiny bit lumpy and there is a rattle on start up - I believe this is a worn chain guide, this soons stops after a few mins.

 

 

Sounds like a  well worn out car now I write this..... but I love it.

Clear the codes and drive the car again and see what comes back.

okay will do - I'll be able to do this on Thur night I reckon.

 

Do you think its worth buying that set of new Beru coil packs? or to early to say this?

 

Thank you

It is a 19-year-old car with 97,000 miles. If proper service has not been done then I think you are looking at changing all the fluids, plugs and coil packs. Checking wear on suspension components and wheel bearings. Tire are obvious as well as damage to wheels.

 

I personally would not touch a small drip from the RMS - too many times changing it can turn out worse.

 

As you might know, I also own an MY 1999 Carrera with factory aerokit - it has 23,000 miles. And it will be very likely FOR SALE soon.

Hey Loren

 

So I re ran the test this morning with the Durametric.

This would be the 8 start/stop since I reset/cleared the codes a few days ago.

 

I know the misfire codes will come back though.

 

I filled with petrol last night and today I have these codes:

 

P1340 Camshaft position with respect to crankshaft bank 1 exceeds

P1531 Camshaft adjustment bank 1

 

So to describe my engine again. The engine runs extremely well once driving, pulls lovely and sounds great. The only noticeable problem is on start up, I get a very light "Chatter" noise from the engine And occasionally (maybe every 2 of 3 start ups)  a quick light Tapping noise - the tapping seems to go away after a few mins of driving. But the chatter is noticeable when i'm on tickover for the duration of the drive.

 

Many thanks,

 

[Loren]

I would address the faults that come back first.

If the misfire faults come back I would replace plugs and coils since you don't know when they were replaced.

Then clear the codes and see if the camshaft issue is still there.
