This is a very common problem with the Citroen Saxo VTR, our remanufactured Citroen ECU's are programmed to work as soon as they are pluged in.
(Years 2003 - 2006)
Bosch Part No. 0261207318
Citroen Part No. 9648483480
This is a very common problem with the Citroen Xsara 1.6 ECU - corroded pins too the ECU multi plug.
Common fault that causes one side or all of the LCD dash to fail, fault can be intermittent but mostly occurs as a permanent fault...
Common faults include complete failure and gauge problems.
Citroen Saxo/Xantia/ Xsara 1.4, 1.8 ECU Part No. SL96-9
Our Citroen ECU’s are programmed to work as soon as it is pluged
in to the vehicle, you do not need to take it to the main dealer for
programming - just plug in and go.
£185 & comes with a Lifetime unlimited mileage warranty*, one from
the dealer will cost you over £500 + vat & programming and will
only have a 6 month
Common failure symptoms:
Poor idle speed
Revving up and down
We have sold units to Citroen Specialists and even main dealers for years now so you can be assured of our high quality standard of work.
Citoen saxo VTI 1.6 16v 1997-1999
Will not rev up properly & vehicle speed severely affected. This model is known for its catalyst problems, the lamna sensor is usually the first part to go when this happens the cat gets soaked with fuel and causes it to become brittle until it eventually breaks up and blocks the exhaust solid - restricting the flow of gas and causes a severe loss of power and top speed, usually restricts the car to a max speed of 30 - 50 mph. in this case the cat and lamna sensor should be replaced together to avoid damaging the new catalyst.
Citroen engines that are still poor at starting from cold but OK at hot starting despite being free of any ignition or starter motor related faults could have compression problems, or problems with the petrol supply. Engines require a minimum compression value to give satisfactory cold starting and this value increases as the temperature drops. Hence an engine with borderline compressions can start OK all during the summer but can refuse to start as soon as winter arrives. Over 150 PSI is OK for all engines though some types of engine design are OK with as little as 110 PSI. Fuel Injection engines increase the petrol supply to the injectors for a cold engine
For whatever system if it is suspected that not enough petrol is the cause of the problem then add about a desert spoonfull of petrol down the inlet tract and if starting is then successfull then your suspiscion is confirmed - conversly if flooding is suspected then disconnect the petrol pump outlet after flooding is suspected to have occurred and starting will again confirm your suspiscion.
Citroen all models 1993 - 2004 onwards - Emission Failures
High CO & low lamna reading. common causes of rich running faults are the lamna sensor or the ECU (engine control unit) both of these parts are relatively simple to check, to check the sensor strip back the insulation on the signal wire from the lamna sensor, this wire is usually black. Then hold the bare wire between your finger and thumb then touch your other hand on to the battery positive the internal resistance of your body will give 1volt at your finger tips which is what the sensor would give out when the engine runs rich, if the emissions come down then you have a faulty lamna sensor or wiring but if the emissions remain the same then the ECU is a possible fault.
