Hello, my name is Luca and I recently owned a 2011 td4 2.4 defender.
With a typhoon with a lot of wind and rain I traveled calmly but after a few days an alarm appeared on the dashboard. ENGINE FAILURE... looking at my Ultragauge I saw that the error is P0101 which corresponds to a problem with the supply air circuit. I thought I had some problem with the air filter and I opened . I found the filter broken and the MAF dirty with small pieces of paper..after cleaning it with a spray and also cleaning the MAp sensor and resetting the alarm on the dashboard, I realized that it is still present in the Ultragauge. I ask you for advice on what I still have to check to be calm. Thanks in advance . |

Hi Ianh, Thanks for your very quick reply.
I disassembled the input curve to the turbo and found small fragments of paper .... I cleaned ... and I did not notice any drop in engine power ... indeed after cleaning the sensors it is more fluid to deliver power .. .but as you suggested I would like to disassemble the ducts before the intercooler and maybe even the EGR valve...I've never done a job like this but I'm confident that it can be done even without lifting the DEFENDER on a mechanical bridge...you what do you recommend me? Thank you |

No need to lift the vehicle. You can detach the intercooler hoses at the intercooler and vacuum the intercooler and hoses to see and clear any filter materials.
No need to touch the EGR. It may be that all is ok and there are no bits of filter blocking anything, the reason you are still getting a DTC is perhaps the delicate MAF sensor has been damaged and needs replacing. Once checks undertaken, clear DTC code, start engine, if code comes back then replace MAF sensor with new Quality part, I.e Bosch. |

Hi Ianh, I ran the checks as you suggested and did a full clean.
I was lucky to find no filter residue and a decent cleaning situation. MAF and MAP cleaned gently and thoroughly with spray brake cleaner and fault reset. I dedicated Sunday morning to work and the afternoon to studying the ODBII Ultragauge that I installed. Ianh do you own a Defender TD4? Has anyone owning an Ultragauge used on a TD4 defender configured the information best? I would like to exchange points of view to better understand what preventive maintenance to do with the information from the Ultragauge. Thank you |
