Xhorse XM38 Toyota C-HR Prox Not Working Solution

 Problem:

2020 Toyota c-hr all keys lost. The customer had purchased one key from dealer. Programmed it with autopropad no problem!! And works fine. Then he asked if I could do a second key and I only had universal xhorse xm38 Toyota so I when and added second key! Now the car took the fob and it show same readings but it only works the remote part not the immo like if the key wasn’t programmed, I’ve already tried messing with the frequency and proximity power nothing changes. The car show 2 fobs programmed but only the oem works, any advice??

Solution:

1).

Frequency issue.

Easy just change the frequency to 314.50 on all frequency options after programming it to the car. Worked for me. Also there are two options for C-HR.

2).

The same thing happened to me a couple of days ago Toyota C-HR 2019 generates the remote PCB 0010 of frequency 314 and there was no proximity I increased intensity and tried everything nothing worked, and so as the key was I put it in the device and generates the PCB 0410 frequency 315, after that the key worked proximity and everything perfect I do not know why but I did not have to do again the add key because so no more already worked the key.

Better use original key for most of them if it is A9.

Xhorse Multi Prog and VVDI Prog Function Comparison

 We will speak about the difference between Xhorse VVDI Prog and Multi Prog programmers. 

If you want to buy a new programmer who can help you read the eeprom and flash, also you want to have it for the engine ECU and for the gearbox, of course, the multi prog is one of the best
business. One of the best deals because of his price. He does not have an subscription. You don’t need to pay every year.

For EEPROM & Flash:

If we go throught the menu on both of them, on eeprom and flash both of them are similar. Like 99% is similar.

For airbag:
Both of these programmers similar. They are not made for airbag.

For engine
In vvdi prog we only have a few of them but in Xhorse Multi Prog we have an entire list.
Clearly the Multi Prog is the winner.

For gearbox
We cannot find gearbox menu in vvdi prog, it only does few chips/mcus. vvdi prog is not makde for this because it is much older device.

Multi Prog supports both engine ECU and geabox TCUs. Multiprog will read, write and clone gearbox TCU, vvdiprog does not.
Multiprog is the winner.

For Dashboard:

On the dashboard we have differences on Audi and also Mercedes, we will read Audi A3 2018, MB 204-212, MB 213, MB 222 dashboard with multi prog. VVDI prog does not.

Multi prog will read and write MQB RH850/V850 cluster with RH850 adapter. VVDI Prog cannot.

For Immobilizer

On Audi, Honda, Ford multi prog has a really great function. For those people who work with Opel you have the immo box function in vvdi prog.

Multi Prog will read Audi A7 BCM1, Ford Mondeo BCM, Honda 2021, Nissan Immo R8F701019, R7F701025, Volvo CEM XC90, S80 BCM, vvdi prog does not.

Another function is the battery. VVDI Prog does not have this function. It is a big plus for the multi prog again.

We take now another function from the software order.

It the big plus again for multiprog is  the steering column on Audi 8 you have the electrical plgm reverse R AC controller on audi4.

We have Porsche steering gear and also the lithium battery on multi prog.

For MCU:
It is a big difference.

It was improved. multi prog supports much more MCUs than vvdi prog.
NXP is also different.
Also very important was on Infineon.
They are quite different.
Multi prog is much easier to search for them. Go to the search menu and you type something and you have it. It does not need to be same selected. This search work really good,

Special Function

Pin calculator is a great function for who need this function on vvdi prog. It is a plus for vvdi prog.

multi prog will read MQB ELV data and decode with vvdi2. vvdi prog cannot.

Xhorse Multi Prog can do IMMO Off, file format conversion, pass generator, it also does checksum correction for some ECUs. multiprog also has scripts functions. vvdi prog cannot do this.

conversion of these files it is for free you don’t want to pay it and it’s quite good function of multiprog.

Update:

They put a lot of updates on the multi prog than vvdi prog. You can update software, firmware and database directly in software.

Xhorse XEPG00EN or B5 Super Remote to Generate PSA ID4A Remote

 Question:

Xhorse XEPG00EN board does NOT WORK on Peugeot, and Citroen cars with 4A chip. Generation is ok, but not work.

Solution:

You cannot generate this option with Xhorse XEPG00EN PSA remote key.

You should use blue NXP remote.

Or use the ZEB510en B5 model vvdi super remote with XT27B chip to generate.

You can also mqb style smart remote it will work.

For example:

2019 Peugeot 2008 key XEPG00EN (XT27B super chip) remote is not working. ZEB510EN B5 super remote works perfectly.
Works absolutely fine.

Xhorse Multi Prog VW MQB Golf7 Chip Configuration Failed

Problem:

Has anyone successfully read mqb r7f701402 golf7 2020 cluster with Xhorse multi prog? I did everything as they said. But multiprog gives error “Chip configuration failed”.

Solution:

This instrument cluster is MQB49.

Detect original key with vvdi key tool and check it is MQB48 or MQB49 key.

If it is MQB49, multi prog will not read cluster and decode immo data.

Only 5A cluster for immo data decoding
5C only for KM. Cannot do immo data.
Mqb 49 is not decoded by any machine.
