Thread: EGR Blank on 08 TDV6

Garry interesting to read your results but agree with ean, i think the answer is in what the MAFF reads ?? ie with the butterfly closed and air being drawn from the exhaust there sould be little air passing through the MAFF, As my Mapp was completly blocked when inspected i feel that it may not play a part in egr stuff. ?? , In your case with the new egr test fitted , i wonder if it it would be the same as blanking off the original working egr before it failed , food for thought . Would be good to know what has exactly failed in your egr,s
As a side note i ordered my Faultmate and used EMS post at the cheaper rate and delivery was 7 days to PO .

It seems to be a mission to remove them, but would be interesting to see if they can be freed up and lubed somehow.

I don't disagree at all - however when I drove it yesterday the new EGrs though not connected to the exhaust but connected electrically to the ECU went though all their cycles as no codes came up at all.

As I always had the intention of getting a BAS map in due course I have decided to go the new system that Pete at BAS has developed. I rang him last night and we discussed my experience yesterday - believes that with the setup I had yesterday the inlet could suck in air from the crankcase and would not be good for the engine - I do not know enough to dispute one way or another. He also said that the ECU does not fault (EML on) with the first fault as it could just be a one off but stores them until a thresh hold is reached and sets off the light/limp etc - this may have been why your experience was initially good and later the lights/limp mode set in and why my experience yesterday was good.

Anyway I have ordered the complete package from BAS comprising engine remap, hardware, blanks and the revised egr remap. As I am the first car that he has come across in his trials with the dud egrs still connected I have made a deal with him not to fit my new egrs at this time and install the new system on the old egrs (afterall that is what it is designed for). If there are issues with the old egrs I will just put the new ones in and hopefully all will be good forever. If the system works as planned with the old egrs I should be able to sell the new egrs to offset the overall cost.

Also we discussed the scenarios that cause EGR failure as it can be as low as 40,000km or I know someone with a D3 and 170,000km and he has no issues - mine has only 65,000km on it. Pete at BAS said that as a general rule town use will clog them up and long distance use will see them lasting longer - the egrs open on trailing throttle and when driving at high speed less soot is laid down.

My car's typical use is driving down to the shops to get a latte (well cappuccino) however my egrs failed on a one day trip from Canberra to Melbourne and back - generally driving at 100-110kph which does go against the thinking.

I should get the gear early next week and I will let you know how things go.

Be interesting to see how it pans out Garry.

Do you have a Faultmate that will accept the remap ? I thought it had to be the top of the range faultmate.

I will just have to wait to see if it can be done thru hawkeye later in the piece.

Cheers Ean

The remap includes the BAS hardware to install and recover the maps. That piece of hardware will also read and clear ECU codes but nothing else.

The BAS interface hardware arrived today with the BAS EGR blanking kit.

I managed to download the engine map from my ECU and send it to BAS. However even though my car is a MY07 it has a 06 ECU Map so BAS will have to work on to make it all work - if they cannot fix it I will have to take the car to the dealer to get the ECU software updated and then send that map to BAS.

In the meantime I started to install the blanks - the passenger side EGR valve was not sooted up much but was slightly open so not fully closing. The drivers side had a bit more soot but it was closed. The pipes were only lightly sooted. Of course things were going well so something had to stuff up - I lost one of the blanks down the side of the engine never to be seen again - it never got down to the undertray. Despite lots of searching with a LED Borescope I haven't been able to find it . If not found when I have look again in the morning I have an old stainless steel saucepan lined up to make another one out of.

As Malcolm Fraser once said - life was not meant to be easy .

What is the process with the BAS unit?
I was under the impression it came pre-loaded but downloading your map sounds similar to the process I just went through with a Viezu v-switch. Makes sense as it is the same base hardware (alientech I believe).

Was 06->07 a turning point in the RRS ECU software or hardware?
Did they sell you something 07-specific?

I'm really looking forward to seeing the outcome - good luck!

The BAS system comprises an interface that can talk to the ECU and then files can be saved to a computer from the interface. You use the interface to take a copy of the map on the ECU and then you send it to BAS who provide a MAP specific to your vehicle. That is emailed back and you load it onto the interface for uploading to the cars ECU. The interface retains the performance MAP and the standard MAP so that when services are done the original can be placed back into the ECU so the performance map does not get overwritten if the dealer does a software upgrade. In theory - if you wanted it and paid for it you could have an economy map, a towing map, a sports map all stored on your computer to be uploaded as needed.

The 07MY went to EU4 specs so major changes in the way the Ecu is set up amongst other changes.

The MAP is not specific to any year but is specific to you own map.

This is confirmed - even though my car is a MY07 and EU4 compliant it has an 06 (not sure if MY06 or 2006) standard engine map.

How does this come about? - it is the map the car came with. Are all Aust 2.7s the same or is it just my car?

Any ideas or thoughts? In theory I guess it is possible to blank my EGRs without having a mod done to the ECU even though my car is MY07.
