The thing to remember about the Alien Tech remap interface units ( ATRIC and BAS boxes.) is that they do not differentiate between tested and untested DTC's which has been a topic of worry of owners on this forum in the past. If you are out of warranty clear the faults and the next time the MIL comes on, plug in the Atric and do a dtc scan and either post the results on here or email them to me and we will take it from there.
P1402 Exhaust Gas Recirculation Metering Orifice Restricted P0234 Turbocharger/Supercharger "A" Overboost Condition P0100 Mass or Volume Air Flow "A" Circuit P2562 Turbocharger Boost Control Position Sensor "A" Circuit P0234 and P0100 are common untested DTC's which I have seen come up numerous times on mine and my mates Puma. I get them more often as I have a Safari snorkel fitted which does increase the air flow into the air box through the ram effect. Pumas regularly Over Boost and Under Boost which is not a worry. P1402 causes me some concern as you have the Atric EGR closed remap and that DTC only shows up when you disconnect the EGR electrical plug meaning no communication at all between the EGR and the EMS. Check the plug is connected properly. P2562 could explain the low power as it is part of the sensor array within the Turbo Modulator which controls the variable vanes. Did we not have a conversation on the turbo modulator harness previously as a couple of the harness wires had broke on yours and you did a repair? Or was that some one else? Coming back to the P0100 DTC, you did fit the new MAF sensor correctly? I am not trying to take the  as they do fit in a set way?

Hi Brian
Thanks a lot for your reply Yes it was me with the cut wires - could be the fault is stored, or that the wiring is badly connected. I will check the EGR connection - clear the fault codes, and read them out again next time it goes in limp mode. By the way it is not often that the Mil light goes on - when the car goes in limp mode. Regarding the MAF sensor, I saw your picture in another post before I changed it 
One more time thank you for the reply - and a happy new year from Denmark Best regards Christian  88 Ser. 3 1980 -sold

Have you had any re-occurrences of the MIL/limp mode since you cleared the stored DTC's?

Edit, posted fault meaning text then scroled down to find them from Brian
lol  ohh the joys of a small Iphone screen.
That said if anyone EVEN ATRIC users need a fault code description my site does offer this service by typing the P code in the search box on the left. http://bellautoservices.co.uk Pete |

Hi again.
I am just returned from a vacation on Gran Canaria - damn it is cold in Denmark. Before I left I cleared the stored dtc and took a short ride - tested again and P2562 and P0100 reoccurred. I will know more tomorrow as I left the car at a good mechanic I know before I went on vacation. I did check the connections to the EGR - but P0100 still reoccurred. Update tomorrow CRJ 88 Ser. 3 1980 -sold Puma 130 - 08- sold 90 200tdi 1991 - sold 88 Ser. 3 1977 200 TDI 110 CC 2003 |

Did you have the turbo wireing checked ?

I did tell the mechanic to do so - hope it is that what is causing the P2562 88 Ser. 3 1980 -sold

P0100 Mass or Volume Air Flow "A" Circuit, is for the MAF circuit and not the EGR. P1402 Exhaust Gas Recirculation Metering Orifice Restricted. Which you logged before is an EGR DTC, has this reappeared? I had it when I ran the Puma with the EGR electrically disconnected by unplugging it from the EGR. Click image to enlarge You also get this one: Click image to enlarge Has the MIL illuminated again? Get your mechanic to check if the dtc's are tested or untested. The P0100 is a common untested dtc but P2562 is not. And as you have had severed wiring at the modulator and you did a repair, that is most likely the cause of the power loss and the first thing I would rectify, to confirm or dismiss. |

Hi Brian.
My mind must still be on vacation - it was the P1402 and not P0100 that also reoccurred - even after checking the egg wiring. Did also ask the mechanic to check it. I never had the P1409 though. 
Can´t wait to get my car back. Regards CRJ 88 Ser. 3 1980 -sold Puma 130 - 08- sold 90 200tdi 1991 - sold 88 Ser. 3 1977 200 TDI 110 CC 2003 |

i again
Got my car back - he found a leak in the exhaustmanifold gasket and it was still leaking a tiny bit between the manifold and turbo - checked the wiring and everything seemed ok. But after driving 10 km - limp mode and Mil light on... starting again everything was ok - but still not the old "pull". Funny thing - I now know I am not imagining it. Sometimes it pulls like it used to - it happened today when I was returning from visiting a friend. When it is at it used to be it pulls from around 1500 rpm - when bad it is from around 2000 rpm  I also notice a change at the top revs - after the remap it pulled like a train to around 3000 and then fading out. But when it is slow at the bottom revs it runs more freely at top revs pulling beyond 3000 revs - know it sounds weird.
My mechanic does not have tools to check for tested or untested DTC´s - fear I then need to visit and authorized dealer $$$ Regards CRJ 88 Ser. 3 1980 -sold Puma 130 - 08- sold 90 200tdi 1991 - sold 88 Ser. 3 1977 200 TDI 110 CC 2003 |

AArrghhh - went to work today - after 50 km it entered limp mode for every 500 meters..... when driving it sort of staggered until above 2300 rpm. Am at the mechanic now - have checked wiring thoroughly.
Faultcodereading now was: P2562 P1402 P0100 P0234 P0623 - generator??? P0046 Could it be that the connection to the ( plug ) ECU is trying to kill me  and making it act weird.
Funny thing when i turned around going home - it acted almost normal again - did 70 km without problems at 130 kmh. Any ideas Best regards CRJ 88 Ser. 3 1980 -sold Puma 130 - 08- sold 90 200tdi 1991 - sold 88 Ser. 3 1977 200 TDI 110 CC 2003 Last edited by CRJ on 16th Jan 2012 12:21pm. Edited 1 time in total |

Checked all plugs - contact cleaner etc. now showing.
P1402 P1643 U0155 Installed original file Then showing P0404 P1643 U0155 Egr seems to be working. Am a bit confused - but for now the car is running

Hello again....
Installed mod. file again - the car is running perfect - after a long run it shows: P1643 U0155 U0300 Do I need to worry - or is it as I hope poor connections. CRJ 88 Ser. 3 1980 -sold Puma 130 - 08- sold 90 200tdi 1991 - sold 88 Ser. 3 1977 200 TDI 110 CC 2003 |

If the defender is running fine now leave things as they are for a day or two and see if it reoccurs. The bad connection theory could be the cause as the untested dtc's show an issue with the MAF, EGR and Turbo boost. The one sensor that is missing from the dtc list is the MAP sensor which can cause the problems you are experiencing with the EGR and turbo boost. Unfortunately without live data to see what all the sensors are reading it is very hard to pin down the cause, the fact that the wiring had been damaged at the modulator and a diy repair was carried out there is no way of telling on a forum if this was done correctly, taking into account the placement of the ferrite fuse which if you remember from your original broken wire post, cuts down RF interference and allows clear comms between the turbo modulator and the EMS. As you have had a few engine issues with your Puma it may be a worthwhile investment to get a nanocom or at the very least a scangauge to monitor the engine sensors and could save you a few quid in the long run?
Out of curiosity did you clean the MAP sensor plug and check its harness as well? Click image to enlarge Sorry for the quick answer but I am just in from work and I need to go out again so I will do a proper answer to your dtc queries later unless someone beats me to it.
Regards Brian. |
