Is that true in all circumstances? As you saw mine had an EGR fault stored last week, and presumably still has it now, so will it be running at a lower performance? What's the logic behind the ECU altering the performance in the event of an EGR problem? Is it a detectable change?Previously:

I cleared your EGR DTC therefore you should be running at 100% Torq-Tune. Most EGR faults are transient so a good dose of brake cleaner (to remove the carbon deposits) should restore the EGR to full operation and clear the DTC's, with blanked-off EGR's this obviously only needs to be done once
The problem is, regardless of whether the EGR's are blanked or not, once a DTC relating to the EGR's is stored, then the engine will operate at a lower performance level - tuned or not. So there are two solutions
You mention that the faults are often transient. I presume the fault code will remain on record once the fault self-clears, but would the performance remain "muted" or would the ECU recognise the fault wasn't ongoing and revert to normal running?
In other words, if there had been previous EGR faults recorded would it be enough to clean the EGRs and fit the blanking plate or would you need to get any outstanding fault codes cleared before fitting the plate?I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

Just a quick update,

Transient faults are stored as hard faults if they occur on consecutive ignition cycles, this varies depending upon the severity of the fault. For EGR's I *think* the threshold is three, after this, the DTC's would need to be cleared
I paid £1.26 for Diesel on the M6 this weekend - that's EUR1.56 I think . At least with the Torq Tune you know the engine is making the most of the fuel Previously:

I can remember when we were all complaining about fuel reaching the £1 a litre mark, won't be long before it's £1.50 and no one will do anything about it

Prices do fluctuate her quite a bit, just looked at my local and it's €1.29 today, It was €1.36 on Friday. They have sales here as well. A local garage had a "tax fee" fuel happy hour the other day, qeues were a nightmare.Knowledge & Reason - the arch enemy of faith

That'd make our UK fuel about 35p a litre without tax BRING IT ON 8) You'd save enough for the Torq-Tune as well

Indeed, and yet another tax scam designed by the Govt. in the Govt's favour. We are told that tax on a litre of diesel is about 65%, what they fail to point out is that, that is the price at the pump, whereas in actual fact duty is now getting on for 300% of the cost of a litre in the tanker.
Supermarkets call that economic model "profit" the Govt call it Tax and the UK electorate sit back and let the Govt "drop anchor in poo bay" every time with complete apathy towards the good reaming that they get and then bitch and moan when Hauliers et al stand up and say "FAIR PLAY ON TAX"
I'm afraid that the UK popuation is now largely a toothless tiger in the face of the UK Nanny State, a lot could be learned from our militant cheese eating surrender monkey neighbours across the Channel.Knowledge & Reason - the arch enemy of faith

Iain, Is there any way of checking for these without plugging in your clever diagnostics kit?
I have to say that mine doesn't seem as spritely now as it did a month or so ago when you did the TorqTune. I haven't been near a dealer (so no overwriting) so either I have gotten very used to the big difference or I've developed paranoia and am inventing problems (or maybe there really is a problem).
How easy is it to have a look see if these EGR valves are sticking from a mechanical point of view (i.e. getting fingers dirty) and giving them a squirt of cleaner?

You could try a 'hard reset' - disconnect both battery cables and link them together for 10 mins, this should clear any transient errors and in some cases may clear 'hard' errors EGR's need to be removed to clean properly, not particularly difficult, just a bit fiddly.... That said if there's an EGR problem the relevant DTC wil be stored anyway

i have a couple of questions, how much more power does this upgrade give and does it cause the vehicle to smoke more. also i already get 30mpg and better so will this be improved or will it do as my defender td5 did and actualy drop after the upgrade (different company upgrade). also will land rover in advertantly erase it or throw a fit the next time it goes in for a service. and how much does it cost.
many thanks jim .
