Removing cam cover on 430 Scuderia, solenoid change...

I have decided to change both cam timing solenoids on the right bank on my Scuderia.

I am trying to hunt down a P1528/P0014 error code and have changed all the cam and crank sensors. I still get the error so this job is next in line.

The job seems pretty straight forward but I am not sure how best access the cam cover. Is this a job best done from the top or can I/or do I need to access it from within the right rear wheel house?

After inspection I found oil in the solenoid wiring loom and the connection between the solenoid and the loom itself. From what I have read in other forums this is not unheard of. If the oil-leak is caused by a sticking solenoid or if the oil it self causes a connection problem, I dont know. Anyone else heard of this oil leaking through the wiring before, looks really strange?

Quite a common problem in the MB 230K engines where oil leaks into the wiring from the cam variator control and can actually work its way back through capilliary action into the ECU and damage it. MB issued a fix that involved an oil block connector inserted in the wiring.

I can't remember if it is the cam position sensor or the solenoid. You really have to see it to believe it.

Not a Ferrari but a very similar issue.......M

Yesterday I finally got to do it and it wasn't that hard after all.

These were the basic steps were:
• Removing the right side engine bay cover
• Removing all the connectors and harness from the cover
• Unplugging the electrical connectors from the injectors
• Unplugging the solenoids
• Undoing the cam cover bolts
• Removing the cam cover and getting it out of the car. This was a little tricky but worked...
• Undoing the screw holding the solenoids and removing them
• Putting the new solenoids in and putting everything else back in place.

In all it took me about 2.5-3 hours :-)
Both solenoid connectors were filled with oil and the one at the bottom just separated without any force. I am pretty sure this was the main problem and the source for the P1528 error code I kept getting.

Engine started up fine no more errors, runs as great as ever, if not even better…

Johan- Glad you found the problem. Much easier than retiming the cams.

Glad you found & fixed the issue! But I'm somewhat baffled the dealership tech could not find the problem and fix it for you to begin with!

I never really let them ;-) The error was random, so we/they wanted to see if it would get repeatable first...

I also saw a challenge in trying to find it myself, which I did

Johan, great that you have conquered the challenge finally. It seems at times you were at a dead end, which must have been frustrating.

Un-freaking-believable! Congrats. Sounds like something that is eons beyond my capability to pull off. Hats off to you.

Took the car for a real test today and the engine runs so much smoother. I might even feel a small power increase, but most of all I can feel the engine running much smoother. It feels a lot easier to modulate the power coming out of turns, great feeling today :-)

Excellent job Johan I'm glad that you finally got these DTC's going away. I didn't came to my mind but this time solenoid issue seems to be quite common on the 430. I got mine also filled with oil a couple of years ago but never got this issue back.

Enjoy plenty your Scud

Johan, Stef- Common problem on other V8s, too. We changed one on my wife's GL 550 that quit working. Engine runs ok without them, but the cam timing is fixed, so power is definitely lessened. At least on the new ones, the variator gear does not usually take out the engine.

I'm trying to help my friend out with his 2008 F430, CODE P1528 will not clear, would you kindly help me with the part number that will clear this please, thank you in advance.


I am unsure if it's the PHASE SENSOR 177673 or the VARIATOR CONTROL SOLENOID VALVE 250646
