Hi Luke,
As a club we get a lot of first time fault posts from folk who are never seen again.
You will get a much better response with an introduction to you and your car.

Common Mistakes - Don't be a newby!

A few tips to get you started on our forum 1. Try an introduction first, simple Hi, and description of your Evoque it's model, year and spec really helps, the Evoque has been out 10 years, there are a lot of variations. Pictures go down really well. 2. Don't be like a troll, it may get your...

As a starter have a new code read now some
parts are fixed and see what is live.

 

Hi Binty,

Thanks for your message.

This is the Evoque, a 2016 autobiography.

Thanks for the advice on re-reading the codes post installation of the fixed gearbox module.

These are the codes that currently appear:

P0673-13
P0730-00
P2702-07
U0001-81
P07DF-07

Thanks,

Luke

 

Hi Luke,
I would concentrate on the U0001-81 that is the high speed CAN error. Google is your friend here but if the CAN is damaged it could result an all sorts of other codes.
When you posted before I saw it but thought maybe it was because the codes were read after the unit was removed, clearly not.
May someone else on here has a better suggestion? I am not an expert just sharing what I would do.
Unfortunately some of the codes could indicate a failed gearbox so you may need an auto transmission specialist who can rebuild it or fit a replacement.

 

When you sent the gearbox module for testing you say it was either too badly damaged or not compatible with their testing equipment. You really need to find which it was, for about £200 you could get one off ebay and see if any codes disappear. £13000 is a crazy amount to quote for a repair, can't be far off what the car is worth.

 

The gearbox module was tested, there was a fault and it was repaired. I then refitted the module but it did not solve the problem.

This is the process I followed:

The transmission control module is what couldn't be tested, highlighted here at point 6:

 

I didn't know there was a gearbox module and a transmission module. Sounds like you need a specialist, not many on here with an in - depth knowledge on what you are trying to solve.

 

Hello,

I have an Evoque 2016 Autobiography with a gearbox fault and the warranty has expired. The car has a new battery replaced 2 months ago.

I took it to the Range Rover service centre and they listed faults for repair totalling £13k. I've taken the car away and the diagnostic fault codes are:

P0673-13
P0730-00
P2702-07
U0001-81
P07DF-07

I stripped out the gearbox module and sent to ECUtesting.com for analysis. They found a fault, repaired and retuned the unit which was refitted but unfortunately did not fix the problem.

The codes above were taken after the module was replaced.

I then stripped out the transmission control module and sent that to ECUtesting.com but unfortunately, the module couldn't be tested. It was either too damaged or wasn't compatible with their testing equipment.

The fault can be described as such:

• cleared the codes
• select reverse gear and generally engages first time and drives.
• Select drive then the error message appears "Gearbox fault"
• Codes appear
• limp home mode activates and drive is easier to select and move.

Before "limp mode" activates, when I select drive, the throttle does not respond and I can not raise the revs.

I changed the transmission fluid, however, when I originally undone the fill port (behind the front passenger wheel), transmission fluid poured out of the fill port, which is odd.

Does anybody have any thoughts on how best I can solve these issues?

Thanks in advance.

Summary: Gearbox fault - not able to shift out of park - result was a bad valve body pressure sensor.

My 2015 Evoque had a gearbox fault at about 75K miles. It would not let me shift out of park. I bought the iCarsoft LR V3.0 code reader and found a fault code on the TCM which indicated that it was receiving intermittent signals from the valve body pressure sensor. The code reader allowed me to read the voltage coming from the valve body pressure sensor in real time. The code reader labels it as "Clutch voltage data". With the engine off and ignition on, it was reading 0.53V. Turning the engine on would make it jump to 0.94V and the gearbox fault would show up on the instrument cluster and the vehicle would be locked in park. I ordered the pressure sensor from eBay for $25 - description is "Oil pressure sensor, Dog clutch 9HP48, 948TE 04752889AA, 0501326481". The pressure sensor threads into the aft side of the valve body. I took the following steps to access and replace it:

1. Remove transmission fill plug first, then drain plug second. Allow transmission fluid to drain completely.
2. Remove air intake filter housing.
3. Remove both inlet and outlet hoses from the oil cooler. The oil cooler is mounted on the forward side of the transmission near the bottom. The coolant system will drain so have a fluid bucket ready. I had to remove these two hoses in order to access the valve body bolts from underneath the vehicle.
4. Remove the valve body cover screws 7x and remove valve body cover.
5. Remove screws 10x that mount the valve body to the transmission. They are a T40 torx bit. There are two different types of screws in the valve body. The smaller, tapered head screws fasten the two halves of the valve body together. Do not remove those. The 10x screws you need to remove have the thicker, non-tapered head. These are the screws that mount the valve body to the transmission and are the screws that need to be removed in order to access the pressure sensor.
6. Once the 10x screws have been removed, use a flat head screw driver to carefully pry the valve body away from the transmission. Alternate between prying from top and prying from the bottom so that it comes out evenly. Mine came out quite easily.
7. Pull the valve body out enough to gain wrench access to the pressure sensor. Remove and replace the pressure sensor. It threads in and just snug tight and remember to connect the electrical connector.
8. Carefully and evenly slide the valve body back into place. Ensure that the manual park/neutral selector on the transmission mates with the top side of the valve body shifter correctly or else the valve body will not sit all the way in.
9. Install the 10x screws using a T40 torx bit to mount the valve body to the transmission. Torque to 8 N-m.
10. Install the valve body cover using the 7x screws. Torque to 6 N-m.
11. Reinstall the oil cooler hoses 2x.
12. Reinstall the air intake filter housing.
13. Fill with coolant from coolant reservoir.
14. Fill transmission with transmission fluid.
15. Roll on.
