Many thanks for your email, unfortunately we do not have any approved retrofit systems for petrol cars to take a petrol car from pre-Euro 4 to Euro 4 equivalence. We are not expecting any retrofit system supplier to develop systems for this market sector due to the limited market demand that would justify the investment. TfL would only accept a retrofitted vehicle if the system was CVRAS approved.
I understand this is considered a cherished vehicle but unfortunately not quite “historic vehicle” tax class/status that would be exempt from the ULEZ. The only way I think TfL would recognise your car as ULEZ compliant is if you could provide the evidence to TfL that the vehicle was now Euro 4 level for NOx (i.e. 0.08 g/km or 80mg/km) as tested over the New European Drive Cycle (even though this has been superseded by the WLTC). This would also most likely be needed to get your V5C document changed to reflect the new NOx value and alter the record on the DVLA database. This is not a simple MOT style test and it would need to be conducted at a VCA approved test facility on a rolling road and not cheap to conduct, this could be around £8k to £10k, so along with the cost of the conversion this test would also need to be covered by yourself or the supplier of the conversion. The test would be equivalent to the one conducted by MG to get the original type approval values.
If you are only driving this vehicle occasionally then it may take quite a while to repay the cost of conversion and the emissions approval test when the daily charge is £12.50. Unlike the congestion charge the ULEZ applies all day every day.
The ULEZ policy is designed to deter the more polluting vehicles from driving in the zone in order to improve air quality for all and with the evidence pointing towards the NO2 levels in London leading to more health issues, including cardiovascular problems.
I hope this helps even though it may not have been the response you were hoping to hear.
Kind regards
Colin

Subject: Rover 4-cylinder K-series engines
Dear CVRAS team,
I am writing to ask about certification for my 1996 MGF. It currently has an EU2-compliant K-series engine and engine/emissions management system. I can up-grade this to the later EU-compliant specification by fitment of the newer engine management, ignition and emissions equipment.
As you know, EU3-compliant 4-cylinder Rover K-series engines are ULEZ compliant by dint of their lower homologated NOx emission.
Can you give me the process by which I can convert my car and gain appropriate regulatory approval? (I will live within the extended ULEZ zone when it expands to the North Circular – I do not use my car for commuting, only for weekend social use).
Many thanks for your help
Rob
