Safety recall for fire risk

I suspect there are some subtle layout differences in these cars that's the cause of the problem. JLR had similar issues when they introduced their new engines and had to move things around a bit in later cars to cure it...

I doubt there were many pre-AdBlue SPA models? Certainly tiny numbers compared to the number of P3 D4s churned out for the lease hire market!

And that really does reinforce my point... why on earth did Volvo initially try to meet those NOx targets without AdBlue?

Honda makes diesels without adblue.

There will be a decent number. It was only introduced in My18 so that's a lot of early cars without it, yet I've not seen a single post about EGR issues over on the SPA board.

It was a lot easier back then. Most manufacturers did the same, the problem was the lab conditions bore no similarities to the real world and in practice, most non adblue E6 cars actually exceeded the limit by a significant margin when driven.

The Euro 6d standard today, whilst the limits are the same as the original version,uses the WLTP test which is a lot more representative and why most manufacturers had to switch to adblue.

Is that an example of the not-so-famous Swedish sense of humour? Oh dear...

Hi guys, first of all, sorry for my english since I'm a user from germany.

I just would like to describe the situation I am in right now.

Two weeks ago I also went to the Volvo dealer to perform the recall R29950 in order to change the ECM Software which should reduce the soot coming from the EGR to not make carbon deposit build on the intake valves. In this case the intake valves would not close properly and the combusted mixture could be blown back to the intake manifold which could melt or deform the intake manifold.

Once the service was done and the new software was flashed, I took my car and went back home. Next time I sat in the car, the engine light turned on and the injection in the 2nd cylinder was cut. Engine was not running round anymore.

So I went back to the car dealer and he checked the engine. After a while he came back and told me that they got to remove the cylinder head to clean the intake valves and and the seats since they are leaking.
So I asked him how he does know that they are leaking after 10min checking the engine without doing a compression or leak down check. Then he told me that they did a electrical compression test to check if the intake valves are leaking. I asked him if he knows how that works because I only know about compression checks which can tell you that there is compression issue in generall without telling you if the intake valve, exhaust valve, glow plugs, injectors or the pistons are leaking.
His answer was that he also doesn't know how that works.

I took my keys and went to another car dealer to to seek a second oppinion.
The other car dealer made the same diagnostic and told me that this is actually Volvo's fault since the original (previous) ECM-Software was producing too much soot which built carbon deposits on your intake valves why I have a leak on that cylinders now.
He told me that the new software should avoid the carbon deposit creation but I was too late already.

After I asked why the older software did not recognize that, he told me that in the new ECM software it's implemented a new diagnostic function what makes possible to detect leakage in the intake valves.

Now I contacted Volvo Costumer service and waiting for an answer how we will proceed now. The car has only 30.000km and has already this issue - unfortunately no warranty anymore but let's see what Volvo will say.

What do you think guys? Who should pay the repair? does anyone has similar issues?

My car had already had 3 EGR fixes including the final(?) definitive one. I was told by the service manager that the EMAP issue was nothing to do with the previous EGR problems, although in retrospect I probably should have pushed for a Volvo contribution to the EMAP replacement which was outside warranty as the pipe being blocked with soot may have been related to my previous EGR problems.

which fault codes did you have in the ECU when the engine management light came on? would be interesting to know

It's would be interesting to know if the cars with problems do anything different like; Drive slow/fast, drive short distances, certain years or completely random. But nobody know except Volvo? It seems like most cars don't have these problems?

I described my issue above but I also noticed that the engine doesn’t combust properly at lower speeds (especially if the engine is hot) which is probably linked to a compression isssue (leaking intake valves). If that happens the engine lights come on and i have following fault codes
P2DF000
P341000
P030000
