Engine system service required

[silverhorse]

Got this message on dash with yellow triangle and warning light. (2005 V70 T5)
Just swapped standard air filter with performance one. Could the car be getting confused with increased air flow or something like that? Or could it be something more sinister?
Can't just be a coincidence that I have changed filter and it comes on. I am convinced it must be linked.
Not running rough. Not hunting for revs at idle. all seems OK
Took battery off for half hour and it cleared but came back 10 miles later.

Any ideas?

[M-R-P]

Hmmm...

Pulling the battery would normally sort this.
I'd check the connection to the maf or anything else you may have disturbed while fitting the filter.
Then put the old filter back on and see if that sorts it.
That would iether rule - out the new filter or implicate it.
If all else fails, get the OBD codes read and cleared.

I hate that orange triangle!

[silverhorse]

Could it be the dreaded MAF? Filter did not seem to be heavily oiled when I put it on.......
Will try old filter and see how I go.
Hope I can keep new filter in though, makes a hell of a noise
With the codes, is there a reader that I can buy for myself to save me being relieved of £50 a time at the Volvo specialists? I am sure I will see that orange triangle again

[M-R-P]

If you have an android phone you can get the torque app for about 3 quid and a cheap bluetooth OBD adaptor for 10 quid.
It won't clear all codes but it'll tell you what's going on.

[silverhorse]

Alas, no android phone. Will scout about on ebay. They must have something on there.
I have read somewhere your sequence for getting rid of a warning light on the dash. Don't know if it was this one, but there must be a way of clearing it and not having to take it in.

[M-R-P]

Unfortunately, the sequence only clears the "time for regular service" message. You'll need to find out what caused the warning and fix it before clearing the code. (although, with some faults, the code will clear itself)

I bought a generic OBDII reader off eBay which works fine on our S60R, think it cost about £15.

If your feeling slightly flush buy a dice and a copy of vida. It's amazing it's what Volvo use.
Its maybe a underlying problem you have with your car, I have this maf error with my air filter, I have changed my maf and it's still faulty, so in my case there is more to it than a Maf

How flush do I have to be? Is that what they plug the car into at the specialist?
I don't think it is an underlying problem, as it started after I changed the filter.
I was giving the car the beans as soon as I fitted it so any new oil may have contaminated the MAF. I am sure I have seen somewhere a 'how to' for cleaning it

That sounds my sort of price!! Excuse my ignorance, but is the S60R more or less the same as my V70 T5? (I am still learning!)
With that reader, do you get the code as a Volvo tech would get it, and then you basically google it??

You can get them for over 100 in the bay and yeah it's what your dealer will use and charge you for every time
.
My problem was highlighted to me when I fitted mine, because the car is taking in more air it's pushing what ever component it is to the point it is failing. Im running standard just now and I have flat spots when accelerating that I never noticed before. The car is booked into mrg in January my not so local main Volvo dealer can't fix it and blame my filter every time but it's not just that, that's the problem

[stribo]

The S60R isn't majorly different engine wise to a P2 V70 T5. The code reader gives a standard OBDII code, which you can find on google, or in the booklet if it comes with one. I fitted a cone, then replacement K&N filter to ours with no problem, if you have got oil on yours, the common way to clean them is with solvent and a cotton wool bud.

This is the reader I use:

Why do these P2 cars seem to throw their toys out the pram everytime we try doing something even slightly non standard to them. Pain in the a**e!

Have you run the dice in graph mode on the maf sensor / boost air pressure have you got any numbers of the air flow/boost air pressure at say 1k,2k,3k,4, I can then see what my numbers are from tick over to boost.

And then you get people like me who can use an MBC to turn the boost up by 60% with no problems

They are indeed a funny creature, the P2.

Martin, yours has a non standard gearbox in it and I bet a pound of s**t it`s been remapped by the old bill

THREAD RESURRECTION ALERT!!!

Right. Finally sorted the problem of MAF fault codes when I put free flow filter on. (hopefully!)
I had everything standard for a long time as I could not get it to run properly with anything but the paper cylinder Volvo air filter, but just before Xmas I thought I would really get stuck in and sort it.

So, smoke test at Volvo revealed;
-cracked intercooler
-MAF to turbo pipe leaked like a sieve
-I/C to ETM pipe leaky
I had already put on all new silicone VAC lines, complete new PCV and 2 new Bosch MAFs and many hours of scratching my head. A few bob had been spent!
Still could not get MAF to go above 8kg/h air flow.
So, as a last resort I reversed the direction of one of the one way valves on the VAC lines and, hey presto, airflow jumped to 15-16kg/h instantly! It has been OK for a week now so I think I have cracked it. It is an internal air leak which will never show up on a smoke test, so difficult to diagnose.
The valve I reversed was on the car in that position when I bought it, so has been wrong for a while.

Thought I would post just in case anyone else is having similar problems. Worth having a look if you are.

Cheers

Nice to see some positive results there mate.
