Interesting comment here on calibration. There is a debate on one of the threads on this forum about this. Most people have just replaced the throttle body but there seems to be a view that it should be set up properly presumably to stop the motor trying to drive past the end points and screw up the plastic gears. 3 x FL1 2 manual + 1 auto no real problems

I'll check why the throttle body has to be calibrated later as the cars in for a service.

I've been told that it's not essential to calibrate the throttle body as it will find it's own position . Calibrating syncs it with the Egr .

Thanks to all your help I have also fixed this problem. I thought I'd share my experience of the OBD2 scanner I purchased in order to identify the code and clear the engine fault light. Also I thought you'd be interested to know about the oem part that is identical to the LR part but at around half the cost.

So, the amber engine fault light lit up on my 2010 Land Rover Freelander 2 TD4. Rather than pay the garage circa £50 to read the fault code I thought I'd take a chance on doing it myself by investing in an OBD2 reader.

After reading lots of reviews I selected the NEXPEAK NX501 as it offered a good balance of performance against cost. I knew and am quite happy that it does not access additional CAN bus modules such as the airbag module, and it will not decipher specific Land Rover codes (you need to look these up).

The unit is well packed and comes with a nice bag which holds the scanner, leads and manual.

The first thing to do is update the firmware, this was straightforward on my Windows 10 laptop. Download the the latest version from the Download Centre (https://www.nexpeaktech.com/service/Download-Center.html) and attach the scanner whilst pressing the 'OK' button. Follow the couple of instructions and the update is done!

Now to business. Connect the scanner to the car's OBD2 socket (located to the right of the steering wheel under the dash) and start the engine. The scanner springs to life.

Then I followed the instructions to read the codes (in my case it showed 'P02E1 - not in database') and a quick Google to this Forum (hurrah!) identified this to be the 'Diesel Intake Air Flow Performance', as you know a common fault which requires a replacement throttle body. As it was an intermittent fault I used the scanner to clear the fault resulting in the warning light turning off.

I obtained a new oem throttle body for £89 via a eBay (Pierburg part number 7.01002.09.0, LR012598) and followed a simple video fitting guide found on YouTube. Job took about an hour.

You can see in the photos that the part numbers stamped on the throttle bodies are (almost) the same. For some reason part of one of the numbers on the oem body has been scratched out, I don't know why this is the case. The Pierburg box was security sealed and so this is definitely how it was supplied to the seller. Note that the throttle body is used by many vehicle manufacturers so the important number is '7.01002.09.0'.

Success! Total outlay £59 (scanner) and £89 (throttle body), and I've the scanner to diagnose future faults. The Main Dealer cost would have been £77 to read the code, and £373 to supply and fit the LR boxed part. This would also have included calibration which I would love to know more about.

Total saving £302!

Just changed the throttle body today, quite a nice simple job and all done in about half an hour.
A good set of t handle torx makes for easy bolt access.
Only unexpected find was the mess left from a mouse getting under the engine cover, never had to vacuum an engine before

Looks like the throttle body needs changing on my car; SDD is throwing almost every fault code available for it and shutdown is far from smooth.

Can't say I've noticed anything odd while driving but I recently got a fault for "EGR stuck closed"- from reading another thread on here I've gathered the two may be related. I've used some Wynns EGR cleaner and no smoke at all came out of the exhaust at any point, either while spraying it in or driving afterwards. Here's hoping it's just a glitch Very Happy

Ok, throttle body changed and working well - all fault codes for it are gone.

Got a new problem now; three fault codes: EGR stuck open AND closed (mmmkay..), and EGR circuit low. Definitely just had the stuck closed code before doing this. I've touched nothing except for the throttle body itself and MAP sensor to get at one of the torx bolts.

I'm suspecting this is just an electrical glitch - is there anything I can do within SDD to fix this? Thanks all Smile

I installed passive mouse traps in the engine bays of all my cars after a rodent ate through the injector loom of my old TT. Jules

Update on the odd EGR faults:

Running the turbo, egr and air path test in SDD (which it "highly recommended") seems to have cured these conflicting fault codes. They haven't returned since I cleared them after this test. Will know for sure after a long drive tomorrow.
