Puma Issues

Hi,

First real post on the forum aside from the welcome post!!
Our 90 has been in the dealer for the past week with a number of issues including rough and noisy engine, poor performance and a very juddery/rough drive. They say they have tried it against another courtesy car and find it to be exactly the same but my wife and I both drove their courtesy cars and they feel very different.

They say they have updated the software and I is all up to date and there are no issues but sti the same. I plugged in the bas box to upload the re-map again and it took it so I know there has been no software update. I then had a look to see what codes are coming up and got the following:
P0100 - mass or volume air flow "A" Circuit
P0299 - turbocharger/supercharger "A" underboost condition
P0404 - exhaust gas recirculation "A" control Circuit range/Performance

Is this an EGR issue? Poor performance and rough running would be a symptom of an EGR issue. The car is two months old...

Thanks in advance!!
James

James, it sounds as if they need to be reminded of technical bulletin LTB00254/2010. This is a modification to the wiring harness for the Turbo modulator, I had the exact same fault codes and this was done. See this topic here:

Hi Brian,

Thanks for the reply.

When you had the wiring added did they also replace the MAF and EGR, or did the extra loom resolve these faults also?

The car was built November 2010 so I am surprised the newer loom wasnt used as standard on the new builds?

Do I go back to the dealer with codes and ask them to look at the TSB? Also do you know if there is any damage to the existing loom caused by the vibrations/stretching?

Sorry for all the questions!

Thanks again,
James

I find quite unbelievable a 2011 landy has those issues. After 4 years still with such cr++py failures? Is quality control managed by a parrot? Puma 110" SW

They replaced the Turbo modulator loom and EGR,MAF and one week later I still have no DTC's showing

This has me worried as it is a Landy after all

The dealers had the Landy for a week as there were a few niggles, I didn't get a chance to inspect the loom, sorry.

Pm me your email address and I'll send you a couple of relevant bulletins applicable your fault codes

Great - really appreciate you help!

So it looks like the fix is to replace all 3? Seems unlikely the maf, EGR and turbo loom are all faulty at the same time though? Do you think it is just one that creates the other 2?

I'll pm you my email - this dealer has had the car nor for two weeks of our 8 week ownership so may try another...

Thanks again much appreciated!!

I was of a similar mindset...so I replaced just the maf

Could see no obvious reason why the loom needed a change...I've changed maf, but I forgot to clear the log..so I'm going to monitor it...next will be the egr if required. Mike
